Fitz gives the Titans the ball and they score. Rather than being angry with Fitz for giving the Titans the ball in the first place, they blame the defense for not dealing with Fitz's bed wetting. Then they glaze over the fact that he can't even make 1 first down with a minute left.
So the thought process is to replace the 11 players on defense rather than the most important one. Sure, that makes sense.
