I dont think anyone is advocating cutting Tyrod. He's certainly shown enough to keep him on the roster. But his position needs to be improved, whether it is by him improving or finding a replacement who is better. Nothing else matters.
Also, Joe Flacco won a Super Bowl by being the best playoff QB of all time. He wasn't throwing the ball 17 times a game. Really, the only real example is Wilson, but he's clearly leagues better than TT. Not even close, really.
