There is a huge difference between a major DI program and the #1 DII program. There isn't a major DI program that is going to take a chance on a guy who hasn't proven he can coach at the next level. There probably isn't a top 50 program that is going to take that chance. If he seriously wants to coach D1 he will have to start as an assistant at a mid level team and go that route or take a a low level D1 team and turn them around.
There is no way that you can tell me that some DI school hasn't offered him a spot someplace. It might not be his "dream" coaching job but that is a different issue.

Who do you think a major program is going to take first a #1 DII coach or guys like Stokke, Asse, Pedroso, Glenn, Kronauge, Woodruff, etc. who have sat back for years waiting for their chance to coach at a major program? These guys either played on a top 5 program, were assistant coaches at a top 5 program, or were on the pro tour.
