I will echo the thoughts others have already posted.
I like getting someone other coaches on the staff have worked with and know well.
I like bringing in a coach with a lot of experience coaching the OL (but not too much; still young and vital). He has a solid track record of success with his OL units.
I like bringing in a coach who is used to being tasked to identify talented players not ready to contribute immediately, but with a lot of potential, and developing them into players. We need to stress development with our players. Coaches used to coaching a lot of HS AA types aren't going to fit in really well in Syracuse.
I like an OL coach with a square head and no neck. The Hawaiian kids should be able to relate to a guy like this.
The adjustment from the weather in San Diego to Syracuse is going to be a big challenge for him. One end of the bell curve to the other. Look what it did to Bud Poliquin.
