The premise of this thread is ridiculous for the following reasons -
As others have pointed out, you don't really need to make excuses for 8-3
The size of the bubble (indicating quality of player missing games) is a lot more important than just the number of games lost - losing Hyde and White for half the season or more is a lot different than losing, and in terms of teams in competition, the Bills have one of the biggest bubbles
The graph doesn't give any indication of players who are playing through injury (and therefore playing at a lower level than expected.) Gabe Davis, Tremaine Edmunds, Jordan Poyer, Ed Oliver, Mitch Morse, and don't forget Josh Allen (just a few.) And again, yes, lots of players play through injuries, but it's clear to anyone watching that we seem to be a bit snakebitten this year in terms of the quality of players who are not at their best due to injury.
Look at the actual scenarios and games we have lost, and it is clear that multiple injuries and missing key players (and depth players behind them) have been key in at least 2 of the 3 losses. Yes, every team loses players, not many can say they have lost as many pro bowl level players as we have and are still in competition for the #1 seed.
