Good hire. He was the hottest name on the market. Might not turn out to be any good as a playcaller, but they will draft their QB and have top 10 picks at WR, TE and RB already on the team. So, he will have talent and a chance to learn on the job.
They also have a good OL in place, which is the first piece that you need to look good as an OC. They just need to find the right answer to the QB question.
