I prefer not to clash with the published opinions of learned colleagues at this newspaper, although the issue in this case is minor, so why not: I don't think ties are a problem in any way in today's NFL.
The NFL started offering sudden-death overtime to break ties in 1974. The rule was modified first for the playoffs and then for the regular season in 2012:
The team receiving the kickoff can win the game on its first possession with a touchdown. If it fails to score, the opponent gets possession and sudden death applies.
If the team receiving the kickoff settles for a field goal, the opponent gets a chance to receive the ball. The opponent can win with a touchdown. If it kicks a field goal, the game is back to a tie and sudden death applies.
The impetus for this change came when the Vikings lost the NFC title game in January 2010 on Garrett Heatley's overtime field goal, after the Saints had received the kickoff.
Obviously, in the playoffs, you play until somebody wins. The limit of one extra period remains for the regular season. One unforeseen factor in going away from straight sudden death in the regular season could be to increase the chance of a tie from minute to highly unlikely.
There were a total of 17 ties during 38 regular seasons of sudden-death overtime from 1974 through 2011. There was one tie under the new rules in 2012, when the Rams and the 49ers went scoreless in overtime and finished 24-24 at Candlestick Park
On Sunday in Lambeau Field, we saw the first example as to how the move away from pure sudden-death could increase fractionally the number of ties:
