You know, I think (italics for a reason, because who the hell actually knows) that if Gase was HC ONLY and not calling plays as well, that he would be a decent head coach. I like the philosophy and culture he is trying to do. I think he is a good leader and the players respect him. I think if he got a strong offensive play caller in here, and focused on coaching the TEAM instead of just the offense, I think we might have something.
Watch Gase during a game. When the defense is on the field, he has no clue what they are doing, because he's sitting on the bench with his nose buried in his playbook. If he could let go of the offensive play calling and focus on being the HC and building the entire team, I think he could be a standout coach.
Unfortunately, I don't see that happening.
