When has anyone suggested that Case should have been the first string qb? Of course not. However, in the latter half of the season when it became apparent to everyone that Mayfield was physically unable to perform the way he needed to, Keenum would have been a better option. Mayfield was a mess, overthrowing, taking too much time, being unsure of himself. Was it the injuries? Hopefully. But a healthy vet would have been a very wise option for at least a couple of those games. The Browns only needed a couple more wins. The Steelers have just beaten the Ravens and should qualify for the playoffs. The Browns are in last. Mayfield needed to protect a lead or bring the team back late in the game. He couldn't do either. In the long run, he is a better bet, but for those games, it was a mistake to keep him in there.
