He was thrown into the OC spot way too soon, when he could've stayed on board and continued to improve as a QB coach. But, Bronco, in his infinite wisdom decided to throw him to the wolves and promote him as the OC.

The same thing is happening with Howell, and at least this time Bronco is starting to take more heat for the terrible management decisions he makes. Fool me once...
