His teams make a LOT of mistakes, as does he himself in game time management. Nobody is perfect.
I think he is learning how to call a proper rushing attack. Clearly, he is still in the learning phase with that ridiculous call to Cobb out of the backfield on first and goal, when he had Lacy and Starks to pound the rock in there. He showed a real lack of confidence there, and I'm sure his team felt that too. Not good. Poor time management to end the first half with the extra time out. These things shouldn't be happening, but they are. Regardless, I think he is a good man, and is trying his best, and he is able to get his team together, at times, to win big games. The 2010 season was huge. Without that, he would be closer to the chopping block.
Personally, I am hoping for staff changes from him, and I am doubting highly that we will see that. That's another big knock on him in my book. I like him, but I'm pretty disappointed in his failings. The guy needs to take some action and make some real changes, as the Head Coach of this team, rather than just talking about what they need to fix with no results. Same thing every year for the last 3 years. That is starting to bug me.
