My Top 5
Based on Jamie's history- he is looking a guy who can win and will do it with integrity. That means there will be no NCAA problems, good kids and a focus on the classroom. IMO that disqualifies Larry Eustachy. Not only does he have the baggage of his alcoholism WHILE at ISU, but the player turnover during the LE era matched the turnover we just saw under McDermott. LE also relied heavily on JUCO kids, not the recipe for stability.
I like some of the Big 10 assistant coaches mentioned by Paul. Each has tutored under a great head coach and runs a style of offense that blends running when possible, but strong half-court sets.
Montgomery - MSU
Gard - Wisky
Ray - Purdue
However, IMO the first choice should be Brian Gregory. He has head coaching experience and got his Dayton team to the NCAA tourney. He should be JP's first call, but I think Gregory will wait for a better job.
The darkhorse that I like is Tim Jankovich. He has a solid record at Illinois State and spent time at 5 Big 12 schools as an assistant.
