Not to defend Chizik, but isn't it a contradiction to say Chizik left ISU "high and dry", but Rhoads came in and won with his players?
I don't think so. I think what you're suggesting is that Chizik left the right pieces in place? Sure. He had some recruiting success, but he clearly lied about being firmly entrenched. Ask the players at the time if they felt abandoned. That's why "I'm so proud to be your football coach" got so much play.
Look at the players we currently have in the NFL. Osemeli, LJ, AJK. All committed to play for Chizik (Klein was in Rhoads' first recruiting class, but he originally committed to play for Gene).
