I read a remarkable statistic the other day. In Russell Wilson's two years in the NFL, Seattle hasn't lost a single game by more than 7 points. Meanwhile, the last time Peyton Manning and the Broncos lost by more than 7 was a 10 point loss to New England in Week 5 of the 2012 season. If either team loses by more than a touchdown tomorrow, it'll be a rare event.
Not really as remarkable as you think. More 'small sample size' than anything else. If you go, on average, 13-3 or 12-4 every year, how many opportunities do you HAVE to lose by more than 7? Lose a couple close games, and you can drag that stat back quite a ways.
Did a 2-second search of the Patriots scores, just as a reference point for another winning team. Last time they lost by more than 7 in the regular season was October of 2011, lost by 8. November of 2010 was the last legit beatdown, lost by 20 to the Browns.
There WERE the AFC title game in 2012 and 2013, (28-13 and 26-16), but the point is that it's rare right until it's not. And with small sample size, you can draw lots of bad conclusions. And in your final game of the year, someone's gonna lose, so guarantees another shot for someone to lose by more than 7.
Hell, the stats show that each team wins about 85% of their games every year, including playoffs. Regardless, someone's gonna lose
