Let's be honest, the only hire that is going to breathe life into the program for next season (or the next few) via a good recruiting class and enthusiasm from fans and alumni is Jim Tressel. He also brings potential stability in that he's been there and done that at a big name school and may just want to settle down somewhere for the remainder of his career.
Are others capable? Sure, but it would likely take years for someone else to do it, and then they'd probably be skipping out of town for greener pastures as soon as the program has recovered. (I know, great problem to have, right?)
You know, five years from now, we may look back at the iCoach era and be thankful because it allowed the stars to align for Tressel to be brought in. In other words, iCoach provided a buffer until Tressel was available. Time will tell.
Given the current state of conference realignments, you have to realize that the window for moving to a bigger/better conference is potentially limited to the next five years. We're a good football program and a basketball arena from making that transition. LP and TW are no doubt aware of this. The stakes for the hire couldn't be higher.
