my opinion. Moore is pretty darn good at the passing game, and the gimmick game. Both of these are needed at times.
I think he is average or below at the run game. He has zone blockers not man so he can't just run load left and load right - he needs to setup runs as well as passes. He is weak at the screen game.
Good mind and good OC yes, but not great. Several QB's like Brady, Manning, even Romo seemed to see the D better than Moore does.
Good coaches script the first X number of plays so they can see what works, and then hammer the grouping that works and force the D to change. I sometimes think the NFL gets to smart for themselves.
I have no clue if he can discipline, motivate, has any clue about defense, or could command respect which are major traits a head coach needs. Can he evaluate talent like was Jimmy Johnsons strength - along with discipline? So I think he would have some growing pains to be a head coach at least and at worse, he can't do the discipline or motivation and ends up a horrid head coach.
