It's impossible for us to know. I think it matters if the guy's a networker who has worked more than a couple places. It's why I assumed that if we ended up with Fisch he'd pull together a very high level, respectable staff. I also get concerned when the staff isn't going to be people the coach has actually worked with - which can happen with a career under pretty much 1 head coach or something. Then you're relying on friends the coach has made at conferences who he's never worked with or screening candidates off resumes others are recommending to him. Some of the staff can be new blood type relationships to keep things fresh. I think that's healthy. But there also have to be a few guys who are in that "know him, trust him, have worked great with him" category.
It is definitely a fine line. I think experienced head coaches can get very stubborn holding on to "their guys" in the face of criticism.
