Sooner you accept that, sooner you will be less stressed. He is what he is. He will ALWAYS (and I mean always), throw the game away if given the ball with the game on the line. ALWAYS. You must have a lead for him to win the game.
Everyone knows Fitz can't win a game by himself. Everyone. But when your top 10 WR in the league drops a ball when he's wide open, that's not Fitz's fault. When the same top 10 WR pushes off and sets you back 10 yards that's not Fitz's fault. Cinci DB got lucky and turned around at the right time, Fitz's fault but what could the fuck do at that point. Do you want to put Geno out there instead?
No, those aren't Fitz's fault. But you don't pay someone $15 mil or whatever to not be able to overcome these things. Fitz is overpaid and Revis is overpaid.
