Bills were only a few plays away from winning every game that they lost. If you look at each individual loss they could feasibly be 10-0, 9-1, 8-2. Yet they also looked like the worse team in most of those losses and deserved to lose all of the games that they did and arguably at least one of their wins. They just somehow managed to keep them close. They are at times one of the worst teams in the league and at times one of the best, and they are capable of both beating the best teams in the league and losing to the worst.
My biggest takeaway from the documentary was that Barry retired because he didn’t want to break the rushing record. I was a big fan of his as a kid and you always heard “Barry doesn’t care about the accolades” “Barry isn’t in it for the individual accomplishments”, as if he was neutral or apathetic about them. But the documentary made it quite clear that he actively did not WANT the individual accolades. He didn’t want to hold the rushing title, he didn’t want the Heisman, he was so deeply uncomfortable with the spotlight that I think he dreaded being the #1 guy on the podium. I think he left because he knew he would break the record that year and he didn’t want it.
That’s not to say nothing else played a role. I imagine if he saw a path to get him and his teammates a SB he would have kept playing. But when that individual accomplishment seemed to be the only thing he was chasing I think he just said Nah.
