The first thing I found is that defining a "breakout season" (in terms that a computer can understand) is not easy. I'll look at several different definitions of the term to try and cover all possible angles.
Probably the simplest way to define a players' breakout season is the first season in which he became a legitimate fantasy starter. Figuring one point per 10 yards and 6 points per TD, and a 10-team league which starts 2 WRs, I set the cutoff at 140 points -- roughly 1000 yards and 7 TDs.
I have career data for everyone who was active during 1998 or 1999. Of those, there were 59 different WRs who have at one time posted a season of 140 or more fantasy points. Here is how those 59 broke down in terms of their breakout season:
--------- Breakout Year ------- 1 2 3 4 5 6 7 8 9 10 11 TOT --------------------------------------------- Number 6 7 10 14 7 7 3 4 0 0 1 596 of the 59 were legit fantasy starters in their rookie season, 7 were legit fantasy starters for the first time in their 2nd year, and so on.
Not a real strong case for the 3rd-year receiver rule here. If a receiver is going to break out, it appears that year number 4 is the most popular year to do so. 3 is next, but only slightly ahead of 2, 5, and 6.
Technical note: this is a judgment call, but I proclaimed a player's "first year" to be the one in which he played his first NFL game. Thus Marcus Robinson gets classified as a 2nd-year breakout even though he had been out of college for three years. I think Robinson is the only guy affected by this, but maybe some of you will inform me otherwise when I post some more complete lists below.
Just for kicks, let's see how that compares to the other positions. I set the bar at 140 points for RBs and 225 for QBs (based on 1 point per 25, 6 per passing TD, and -3 per INT):
--------- Breakout Year ------------------- 1 2 3 4 5 6 7 8 9 10 11 12 13 TOT ---------------------------------------------------- WR 6 7 10 14 7 7 3 4 1 59 RB 21 12 7 5 3 2 2 52 QB 3 16 5 7 5 1 1 1 2 1 1 1 2 46These numbers are what we'd expect. While WRs can take awhile to develop, good RBs are generally good from the start. QBs are a crapshoot, although I was surprised by how many broke out in their second season. That suggests that the possibility that some of this year's sophomore class could well be viable starting QBs this season.
I have heard it suggested that it takes longer for big WRs to break out that it does for speed guys. So I broke the above 59 WRs down by weight:
--------- Breakout Year ----------- 1 2 3 4 5 6 7 8 9 10 11 TOT ----------------------------------------------------- 195 Lbs and up 2 4 6 7 4 2 3 2 1 31 Under 195 4 3 4 7 3 5 2 28These numbers do lend support to the above hypothesis. More of the burners made their splash earlier than the big fellas. Still nothing at all magical about year #3 for either group, though.
OK, now let's set the bar a little higher, and let's say a breakout season occurs when you reach 180 fantasy points for the first time. There are 32 active (this year or last year) WRs who have accomplished this. Here is when they did it for the first time.
--------- Breakout Year ----------------- 1 2 3 4 5 6 7 8 9 10 11 12 13 TOT -------------------------------------------------- Number 1 4 8 6 2 2 4 3 1 1 32That's Irving Fryar who "broke out" in his 13th year, in case you were curious. With this stricter definition of breakout, year 3 does indeed become the most likely breakout year, but not by much.
OK, now let's look at things from a different angle altogether. Let's say a breakout season occurs when a WR increases his fantasy points by 100 over the previous year's figure. This is not a perfect definition (as you'll soon see), but it captures most of the seasons typically considered in these kinds of discussions. Here is the complete list of such seasons (again, I only have data for players who were active this year or last year.). The last column (labelled "Exp") tells you which year in the player's career the given season was.

Note that more players made this large leap in their 2nd or 4th year than in their 3rd.
A 100-point increase is a lot to ask, so let's check out the list of WRs who accomplished a 50-point jump in fantasy production from one season to the next:

It seems a bit silly to call Terance Mathis' 1998 a breakout year, for example. Anyway, for those of you keeping score, that's 11 breakout seasons in year 3, 10 in year 4, and 7 in year 2.
To put it bluntly, the evidence in support of the 3rd-year receiver rule appears to be underwhelming at best. By no means am I claiming that this study closes the book on the issue. All of my definitions were admittedly flawed, and I wish I had a more complete set of data. But unless I see some hard evidence in support of the 3rd-year receiver rule (I've never seen any, by the way, just examples), I'm going to cross it off my list of things to consider.
