DeBerry is at AFA for life. He would have trouble with the distractions at a "real" university.
I'm thinking Chow will wait till he gets a high profile program. Great offensive mind, but I am not sure he wants to build a program.
I know why you are attracted to Neweasel, but you don't need the bad publicity he would bring.
Solich and Willingham would be great choices but I think Willingham will want something with more potential for quick success.
You might want to look at Bo Pelini (sp?) - DC at Oklahoma who finished out the season at Nebraska last year and thought he had the perm job.
