Bowles is the head coach. He is graded on the offense, defense and special teams. So Morton doing well 100% has a bearing on Bowles as a head coach.
People are saying Bowles is conservative at the half. Weeks ago he got killed for not being conservative at the half. Who knows what Morton said, he could have said McCown is hurting, Petty sucks, let's just sit on it at get to the half.
At the end of the season everything has to be evaluated. My vote right now would be to bring them both back. Because blowing things up every three years hasn't worked out. That said, right now Bowles and Macc both suck.
