As long as Rex is coach and Tyrod is healthy, Tyrod with start. The only way we see change, barring injury to TT which I do not want to see, is if Tyrod and Rex both go down together.
I am convinced at this point that the Bills will miss the playoffs but that the Pegulas will keep Rex and Tyrod. We are doomed to mediocrity for at least one more season. If Rex/Tyrod manage to get them to a one-and-out playoff game, we are doomed to Rex as coach and Tyrod as QB for at least two and probably three more seasons, no matter how bad they play.
For the first time in thirty years, I am making no effort to watch the Bills games every Sunday. I still care for and follow the team, but I see no chance of a title or even a deep playoff run with the current coaching regime. Rex is a mediocre coach. He's entertaining, he knows a few things, but he is inflexible and limited. His teams will always take at least 8-10 penalties per game. Some of those penalties will be egregiously stupid backbreakers, but nothing will change the next week or next month or next season. His teams will always take unnecessary time outs because of confusion of slow communication. Clock management will be spotty to terrible. They will always look lost at times during the play, especially against elite teams.
The players generally like him and play hard for him, but they don't play smart. He will always go for a run-oriented offense and accept mediocre QB play. He gives great press conferences. He has the macho swagger that many fans think indicates a good coach but that is not correlated with winning.
And this package will be just convincing enough for many fans--and the Pegulas, in the end--to keep him on longer than is warranted by the results. I'm not saying it's easy to find a superior coach, but Rex is not one and never will be one, and his teams will be a reflection of the man.
