My point is not that Fitz will win championships with the Bills. My point is Fitz is one, the most important one, of several examples why the Bills don't win as much as their talent would suggest they should. Gailey is so right when he says they (not just Fitz, "they") need to learn how to win. But when he says the he's really pointing the finger it himself. What he should say is he hasn't taught them how to win. He hasn't lead the team in a way that would get a stop against the Titans to win the game, to fill their lanes to prevent a punt return for six. They aren't winners. I'll agree, Fitz isn't a winner, he's part of the problem, and he's a big part of the problem, but Fitz wasn't primarily responsible for losing to the Pats or the Titans.
This team can and should win more games with Fitz at QB. But it needs someone better than Fitz if it's going to win a lot of games.
