McCarthy is only one part of the decision to have Hundley be the backup QB. Thompson has final roster say. The decision to stick with Hundley isn't going to hurt him with Thompson.

A malfunctioning offense for the rest of the season might.

But the biggest bone of contention will be the defense. The 3rd down problem has been there through a LOT of years and personnel. Thompson has said he doesn't like telling a coach who his assistants should be, but if the team decides Capers needs to go, McCarthy might balk. He has gone to the mat publicly for Capers before.
