The NFL instituted sudden-death overtime in 1974 where the team scoring first in overtime would win the game (and modified that in 2012 to give a possession to each team unless the first score was a touchdown or non-offensive score). If both teams are tied at the end of overtime, the game counts as a tie in the standings (and is counted as half of a win when calculating standings). The following is a list of all games that were tied at the end of overtime.
