The best hire we could get outside of Whiz. The problem with Whiz is that he would have probably been hired anyway next year. Heck I am sure that would have been the case. He was getting interviews after the horrible season they just had. People that don't like this is just because he is not a big name. I remember Cutler talking him up, he managed to stick on 3 coaching staffs on the same team. That must mean something. All the positions he has coached have been successful under his watch.
You can take this to the bank. He will be a HC in about 2-3 years. This lets us continue with the current system and better yet, when the time arrives for Brock to take over, we should know for sure if he is the QBOTF.
