No, we have we coaches here that can coach them. During Brewster's tenure here, he has hired assistants and coordinators that are accomplished and in demand. If anything should be taken from Brewster's staff, it's that coaching is highly overrated, that really is all about the Johnnys and the Joes more than it is about the X's and the O's.
I strongly disagree, if the point you are trying to make is that top flight players are more important than top flight coaches. In the Big 10, unless you are OSU, Michigan, PSU, or Nebraska, you will rarely get the top flight players. You need a coach (and staff) who have a system they all understand, recruit for that system, and coach each player to reach his maximum ability. That is what Alvarez, Ferentz, etc. do and that is how the non-Big Four succeed in the Big 10.
Alvarez' first Rose Bowl team had a ton of Wisconsin and/or not highly recruited kids on it, but they believed in the coaches and the coaches made them all better players. Get some guys who can coach - I haven't seen it from Brewster in the games I've seen. Then have the coaches recruit with a believable program - not Pasadena in three years. Keep the expectations realistic - I'll make your kid the best football player he can be.
