Super Bowl notes: Stat of the Year and Updated SRS Standings
My vote for Stat of the Year, courtesy of Big Lead superstar/PFR family member JKL: the Packers haven't trailed by more than seven points at any point this season. Let's take a look at Green Bay's six losses:
- In Chicago, the Packers got up 7-0 and 10-7, trailed 14-10, took a 17-14 lead, and lost 20-17.
- In week five in Washington, the Packers led for most of the game before the Redskins scored 10 fourth quarter points to force overtime. Washington won 16-13. Yes, Washington beat this team.
- The following week, the Packers trailed 7-3 and 13-10 against Miami, and an Anthony Fasano touchdown reception gave Miami a 20-13 lead. Aaron Rodgers rushed for the tying score, but Miami won in overtime, 23-20.
- In week twelve, the Packers lost another close one in Atlanta. The teams exchanged scores all game, alternating with a Falcons field goal, Packers field goal, Falcons touchdown, Packers touchdowns, Falcons touchdown, Packers touchdown, Falcons field goal.
- In Detroit, playing the majority of the game without Aaron Rodgers, the Packers lost 7-3.
- The next week, a loss in New England without Rodgers looked disastrous in the standings but respectable on the field. The Packers got up 3-0 and then 10-7 and 17-7. Two Patriots touchdowns made it 21-17, but Green Bay responded with another touchdown. The Patriots scored last, winning 31-27.
The Packers never trailed by a score in any of their 13 victories, either. Even trailing early wasn't an impediment to a big game, like when the Falcons went up 7-0 in the playoff game. So how rare is it for a team to go an entire season without trailing by more than 7 points? As you could guess, extremely.
The 1942 Redskins. George Halas' 1948 Bears. And the 1962 Detroit Lions, a team that had to compete with the buzzsaw that was the 1962 Packers. Head to head, the Lions outplayed Green Bay's greatest team Under Vince. Detroit dropped the first game in Green Bay 9-7, on a field goal in the final minute; the Lions crushed the Packers in the rematch, racing out to a 26-0 lead before a couple of late scores made the final tally 26-14.
Those three teams are the only teams since 1940 to never trail by more than 7 points, unless the Packers keep their streak going in Super Bowl XV. Green Bay would become the first team in the Super Bowl era to never trail by more than a touchdown, an incredible feat in any season, but especially so given the injury-plagued year the Packers endured. What's the biggest margin some other great teams have faced? The table below lists the "low point" on the season for each of the first 44 Super Bowl champs:

The '84 49ers and '72 Dolphins combined to lose just one game, and neither faced a deficit of more than 10 points at any time during the year. Outside of them, only Hank Stram's '69 Chiefs didn't have to deal with a two-touchdown margin on the scoreboard at least once during the season.

I'll admit it: I'm always curious to discover the opening point spread for the Super Bowl. This year, the line opened at Green Bay -2.5, meaning the oddsmakers view the Packers as a slight favorite. This surprised a lot of people, considering how the AFC looked like the stronger conference all season and Pittsburgh's history of dominance in recent years. The Packers were hot, of course, but still have the taste of the 6 seed in the mouths of some. Who wouldn't have been surprised? Anyone looking at the updated Simple Rating System standings. Here they are, through the conference championship games:
| Team | Gms | MOV | SOS | SRS |
|---|---|---|---|---|
| New England Patriots | 17 | 11.5 | 3.0 | 14.5 |
| Green Bay Packers | 19 | 10.3 | 2.0 | 12.3 |
| Pittsburgh Steelers | 18 | 8.3 | 1.7 | 10.0 |
| New York Jets | 19 | 3.9 | 3.5 | 7.4 |
| Baltimore Ravens | 18 | 6.1 | 1.0 | 7.1 |
| Atlanta Falcons | 17 | 5.6 | -1.1 | 4.5 |
| San Diego Chargers | 16 | 7.4 | -3.1 | 4.4 |
| Philadelphia Eagles | 17 | 3.2 | 0.9 | 4.1 |
| Chicago Bears | 18 | 2.6 | 1.3 | 3.9 |
| Indianapolis Colts | 17 | 2.5 | 0.0 | 2.6 |
| New York Giants | 16 | 2.9 | -0.8 | 2.1 |
| Detroit Lions | 16 | -0.4 | 2.4 | 2.0 |
| New Orleans Saints | 17 | 4.4 | -3.2 | 1.2 |
| Tennessee Titans | 16 | 1.1 | -0.3 | 0.7 |
| Miami Dolphins | 16 | -3.8 | 4.1 | 0.3 |
| Oakland Raiders | 16 | 2.4 | -2.6 | -0.2 |
| Tampa Bay Buccaneers | 16 | 1.4 | -2.4 | -1.0 |
| Minnesota Vikings | 16 | -4.2 | 2.6 | -1.6 |

| Houston Texans | 16 | -2.3 | 0.3 | -2.0 |
| Dallas Cowboys | 16 | -2.6 | 0.4 | -2.3 |
| Washington Redskins | 16 | -4.7 | 0.8 | -3.9 |
| Buffalo Bills | 16 | -8.9 | 4.2 | -4.6 |

| San Francisco 49ers | 16 | -2.4 | -3.6 | -6.0 |
| St. Louis Rams | 16 | -2.4 | -4.6 | -7.1 |
| Seattle Seahawks | 18 | -5.7 | -3.2 | -8.9 |
| Denver Broncos | 16 | -8.1 | -1.2 | -9.4 |
| Arizona Cardinals | 16 | -9.1 | -4.0 | -13.0 |
| Carolina Panthers | 16 | -13.3 | -0.4 | -13.6 |
That's right: the SRS views the Packers as 2.3 points better than the Steelers, as they've been the second best team in the league this season. The Packers' SRS score was aided by the best post-season game of any team, a 27-point road victory against a team 4.5 points better than average. The best win of the year came from the Patriots in their 45-3 shellacking over the Jets. The home victory means a margin of victory of 39 points against a +7.4 team, for an SRS grade of 46.4. The Raiders 59-14 win in Denver (48, -9.4, 38.6) and the Patriots' 36-7 win in Chicago (32, +3.9, 35.9) round out the top three.

Only three teams in 70 years have never trailed by more than 7 points in a season -- and two of the three did it in the same year in the same division. Go figure.
Sorry Jim, I think you misread it. Washington did it in 1942, Chicago did it in 1948 and Detroit did it in 1962. And now Green Bay did it in 2010/2011 (j'espere).
Neat stat! But...
This year, in games decided by 7 points or less, the Packers were 6-6, including playoffs. 4-6 in the regular season. The point is, regardless of "keeping it close," they were still a sub-0.500 team when they did. I don't know how this stacks up against the rest of the NFL, but that doesn't scream "great team" to me. It screams average: when in a close game, their chances are at the league average.
Confession: yes, I'm a Bears fan.
I agree with Dan, clearly teams that are not great and have SRS's of over 12 do not make the Super Bowl.
Sorry to nitpick, but the Packers actually DID trail the Fins early 7-3 and 13-10, Just saying
But yeah, that stat is truly astonishing. Thanks for bringing it to the light of day
It's stuff like that which makes me visit here every day.
Good catch, DolFan. Rest assured, the rest of the post is error-free
I've updated the blog post. Thanks again.
Regardless if the packers were sub .500 in close games, they were still in the games. They put themselves in a position to win each week which obviously not every team can say.
Confession: yes, Im a packers fan and yes it was awesome to see gb beat chi.
I think that a team that goes 10-6 with the following scores:
10x 45-0 victories
6x 17-16 losses
is better than a team that goes 16-0 with the following scores:
16x 17-16 wins
I fully agree that the standings shouldn't reflect that, but if I had to choose who would win a game between those two, I'd pick the first team every time. "Ability to win close games" is about as intangible a skill as it gets.
Dan -
I don't see you advertising how incredibly lucky the Bears season was. If Calvin Johnson doesn't worry about showboating, Bears aren't in the playoffs. Should I mention the four third-string QBs the Bears played against? Or the fact they lost their only two road games to teams with winning records? Or the week they played Philly, the Eagles lost both starting corners in practice that week?
And lastly, allow me to add, the Packers are NFC champs and playing in the Super Bowl while the Bears are trying to figure out if they have the QB they thought they had.
Have you guys looked at how predictive SRS tends to be? Rather than how close it is to the spread (which isn't a true handicap as it is partially based on the perception of the betting public), how close does it come to predicting the final score?
Interesting that the Browns entered the NFL in 1950 and didn't fall more than two touchdowns behind in a game until the last game of the 1953 season, when they had already wrapped up the division title.
Are we sure the Packers didn't trail by more than 7 in a win? Just curious since no stats were given for wins
Jane,
Here's a look at the score after all 24 touchdowns the Packers allowed this season: http://pfref.com/tiny/DX99z
Only three touchdowns were scored against Green Bay in tie games, with the remaining 21 coming while the Packers held a lead. Obviously you could go up by more than 7 points by scoring a field goal or a safety, but I quickly ran through each game and didn't see that happen.
Chase
@BSK
I actually semi-religiously used SRS as a predictive model in my office picks league from weeks 13-16. It was a "seeded" league, where you put 16 points on the team you think is most likely to win, 15 on the second-best, etc., down to 1 on the one you have the least confidence in. I generally ranked those by the difference in SRS, giving 2.0 (after I read a post saying that HFA was about 1.9 in 2010) to 2.5 (before I read that post) to the home team.
I may post an in-depth description of how it turned out, but the nutshell version is that while it worked fairly well and helped me pick a few upsets that people wouldn't have thought of just by looking at records (like Detroit over TB in week 15), I didn't win the league in any week, and, in fact, got hammered in week 16. I think SRS overvalues big wins (and losses) a tad ... I seem to recall something about a 21-point "ceiling," but that may have been in relation to college games, and I think that skews the rankings somewhat.
And, of course, SRS only looks at the past in terms of player injuries and teams' general trends (Tennessee still looked pretty good the second half of the year, SRS-wise, and finished with a 1.0 SRS, but there was no way I was picking them!), so you still have to do a little "real" homework. Overall, I'd say the system worked reasonably well, but you still need a little actual thought.
the spread (which isn't a true handicap as it is partially based on the perception of the betting public)
I'm no gambler, so correct me if I'm wrong. But it's my understanding that the spread -- at least the initial spread -- is very much a true handicap. If the public subsequently bets one way, the line will move. But if they opened the lines trying to pander to vast numbers of betting Notre Dame or Cowboys or Red Sox fans, the sharks would take advantage of those opportunities and make a killing.
re: 14
I based my picks from Week 13-17 on point differential and schedule strength and went 54-25-1.
I went 82-88-6 from Weeks 1-12 using no system.
JWL-
Was that to win the game or cover the spread?
JT-
The line always takes into account where they think the money will lie. They can't afford to get hammered by early action if their spread is off. They take into account both the public money and the shark action. Of course, more often than not, the "betting line" will be close to a "true handicap". But the lines makers are always looking at where they anticipate the money landing. A big reason the Packers are favorites right now.
If the Packers win this game by never trailing in the 4th quarter (so no comeback win like the last 3 SB champs have had), they'll be just the third team to ever win the SB without making a single 4th quarter comeback win in the regular season and playoffs.
Can anyone name the only two SB winning teams to do that?
The last 7 SB's have seen at least one team in position to make a comeback in the 4th quarter. I have little reason to believe the same won't be true for this game. That's why I like the Steelers if this game goes that way, because the Packers of the last 3 years are pretty poor at coming back (just 3 CB wins, all against losing record division teams and never from a deficit larger than 2 points) and actually closing the game with a win, and it's been various factors as the cause for that.
I'm also stunned at this stat...you're going to win some and lose some, but being within a score of your opponent for 18 straight games is nothing short of amazing...it makes you wonder "what if" had the Pack kept Grant/Finley/etc all year...perhaps all the adversity inspired their 'win or go home' mentality these past 4 games, and they wouldn't even be here? I love football.
That's also a reason I favor Pittsburgh in this game, if it's close, I trust Roethlisberger to get a late score much more than I trust Rodgers, we've just seen Ben do this time and again over his 7 seasons in the league.
#19
Um no, actually I think we just saw that the Steelers can win with little to no passing offense.
Rodgers was off too but over the year he has been playing pretty well with a bad running game, which is something I respect. Ben is lucky he is even in the Superbowl after that performance. Obviously both teams have a shot. I thought the recent pro-football-reference post on how elite QBs play against the Steelers is interesting though.
@#9 (Tom Football). I brought up my Bears' fandom only out of full-disclosure. So let me waste my time and clarify: the Packers were a better team than the Bears this year. Happy?
That isn't the point of the first part of this post, though. The stat presented tells me a couple of things:
1. The Packers were never in a deep deficit at any point in the season. That is, regardless of the team they were playing against, they were never outside of a one score game. That is extremely fascinating and very, very rare and pretty impressive considering things like starting their #2 QB against a team that looked unbeatable (the Pats) and keeping up with them.
2. Their record when not blowing out teams was near 0.500. I don't disagree with Jason's (#8) statement above, but that's not what that team was this year. A better scenario is:
4x 45-0 victories
6x 17-16 wins
6x 17-16 losses
This tells me a team is incredibly well balanced and about 25% of the time, both sides of the ball are playing at their full potential. But it also tells me that their ability to 1) score late or 2) prevent scoring late is average at best. They lost to the Bears on MNF because they allowed a 2:15 drive on 7 plays at the end. They lost two overtime games because their defense allowed significant drives for field goals.
This isn't a damning thing; All teams do this stuff. But calling this "keeping it close" stat as some sort of sign of greatness is wrong. They're a great team for other reasons (the ability for the offense to put up 30+ on any given day, the defense in general, etc.), not because they never get down by more than 7 points.
Interesting stat, but really more of trivia.
You can't read too much into it. Before the BCS Championship, Oregon had never trailed any game. Auburn, of course, trailed Alabama by 24.
Re: Dan #21
I heard this stat on the TV broadcast of one the Packers' playoff games, and the thought I had was this--they are pretty good, and never are out of the game. This means that they are well balanced--in other words, their offense gets consistent scoring to support the defense when it's playing below par, and the defense stuffs the other team to support the offense when it's sputtering. I don't think it's lucky at all--I think it supports SRS' opinion of the team--the 2nd best in the NFL, and the best NFC team.
BTW, if you don't read Football Outsiders, they have an older article that talks about close games and blowout games. The short version is that great teams dominate the bad teams on their schedule, and don't give them chances at an upset. Winning the close ones is pretty much a function of luck, a good long-range FG kicker, refs missing one in your favor, etc. In that respect this year, GB has actually been below average, as you mention. This means that their W-L record will be worse than their true ability. I think the Steelers of 2007 and GB getting to the SB this year reflect that--both teams W-L record were not reflective of their true ability. We can all site teams that were the reverse (ATL this year, for instance).
@Joseph
Agreed, whole-heartedly. Really, despite my hatred of the franchise, I'm not trying to say they were lucky or bad or anything. I'm treating this stat as objectively as I can, and while it is INTERESTING, I don't think there's proof that it is a formula for success. Another way to maybe phrase my thoughts would be, "Staying within 7 points does not guarantee wins."
Remember the 2001 Lions? Probably not. But I remember a team that couldn't buy a win even though they were in most games:
http://www.pro-football-reference.com/teams/det/2001.htm
Betweens Weeks 5 and 13, they lost every game by one score or less. One of those games was by 8.
This isn't the same as the 2010 Packers stat since there's probably games where the score was only as close as it was because of garbage-time points. But that was a not-good football team that went 9 straight weeks where they "kept it close," or at least made a last-ditch effort to. While I have made the argument that that year's Detroit team was the best 2-14 team in NFL history, it doesn't mean they were good.
So, in summation: staying in games isn't the same as winning them, even when you're a very good team, like the 2010 Packers.
RE: 17
Against the spread. That's why there were 7 pushes in my total record there.
Good article, too bad this was already figured out a month ago by a user named Waldo on footballs future. Who is definitely not this guy.
If you hop over to Advanced NFL stats they will prove to you that you should give no weight to teams that "win close games". And what more that it is very predictive of future winning to "stay in games". Its capped off by the fact that teams that lose close games in the regular season stomp all over teams that won close games (i.e. got lucky) come playoff time.

RE: #27
Can't say I agree with that study, but of course I've disagreed with Jim Glass on the subject before.
Two problems I see: final score is not good enough to indicate whether or not the game was close. The Saints beat the Colts by 14 points last year, but that was one of the closest SB's in history. That's one problem. The other is using playoff results, the one and done situation, to decide what factor all those regular season results had. If this was a best of 7, I would be much more inclinced to buy in, but anything can happen in the NFL playoffs because of the one and done.
I don't think Green Bay blowing out Atlanta 48-21 had anything to do with the Falcons winning a lot of close games and GB not doing that, and having a larger points differential. I think Matt Ryan throwing two bad picks, including one of the worst you'll ever see before halftime blew that game wide open for GB. Ryan was 24/28 and in control when they played in the regular season, a game with a low score, but also with limited possessions and efficient offense from both teams.
There's nothing to agree or disagree with. Its a study, it says what it says with as much force as it has sample size. It has a large sample size. Its interesting that one game can be analyzed like that. But that's why the study isn't based on one game. Its based on ALL the games for many years.
Also, that's the point. History has shown that football is about how often you play efficiently. Teams that play efficiently more often win more games in the future then teams the play less efficiently, regardless of past wins and losses. The Falcons were a good team, but they weren't as good as the Packers by any measure we have other then Wins and Losses. And since Wins and Losses do not predict future wins and losses as well as the Simple Ranking on Pro-Football Ref here or the medium sophistication system at Advanced NFL Stats, why would anyone put any stock in Record over these other systems.
You can disagree with the methods used in the study, and I think using the final score for just about any study is a flawed one.
Re #18, I would guess that one team was the 85 Bears. They blew out everybody in the playoffs that year I think.
Re #30: Scott, I kind of agree with you here. But my theory is that most games with a close final score are games that either team probably could have won depending on one or two plays that could have gone either way (dropped interception, missing a first-down by an inch, missed field goal, etc.). While blowout games are generally games that only one team had a chance of winning. Because of this, records in blowout games probably tell us more about the quality of a team than records in close games. (Yeah, occasionally there are times when a game is a blowout but the other team comes back to make the game close in garbage time. But if they get close enough, this still probably tells us the matchup was close, because if one earlier play had gone the other direction maybe the outcome would be different).
Chase - the Milwaukee Journal Sentinel says the 1969 Vikings never trailed by a TD as well.

Will,
This post includes post-season play. Minnesota lost by 16 points in the Super Bowl.
The Packers made it through this Superbowl, and their 7-point max deficit is still intact.
