We have plenty of these threads already, but as to your list:
1: Bill Coen, I just don't think he's a good enough recruiter. He has had some talent, but the depth of NU's teams were always godawful. It's why they collapsed down the stretch of every season. I don't know if he'd be up for the rigors of the A-10 arms race. We might become the new Dayton of the A-10 -- start off strong every year and wind up 8-8 or 9-7 after our teams run out of gas.
2. We aren't getting Tommy Amaker, unless GMU Law suddenly becomes better than Princeton Law.
2: Bruce Pearl, really? Just what we need, a guy who will kill us with recruitment violations.
3: I doubt Wojo comes here. I'm thinking a Roy Williams situation.
4: Pat Skerry, unless we are willing to pay him BCS money he doesn't leave Towson.
5. Grant Hill, really? I mean, if you're going former NBA player, why not Damon Stoudamire? At least he has a few years under his belt under Pastner at Memphis and Arizona.
Solutions:
Solution One: We could retroactively do what we probably should have done and hire away one of Miami's assistants in a kind of time travel promote an assistant coach way: I think most here wouldn't mind seeing Caputo or Konkol in that role.
Solution Two: We go back to the "proven head coach" option and poach a guy who has had sustained success at a lower mid-major school like Rick Byrd from Belmont (although he'd probably be a caretaker coach and might just retire at Belmont) or Steve Prohm from Murray State (although I think Murray State's facilities are probably better than ours now, but we still have the benefit of playing in a much better conference than the OVC).
Solution Three: The "up and coming assistant" route. Find a few head coaches who play a style you admire. I love Beilein's offense and defense at Michigan so I wouldn't mind giving LaVall Jordan a chance (reportedly a great recruiter, so that's a plus).
