My list has always looked like this.
- Frost
- Fuente
- Campbell
- Bielema
- Jim Tressel (Sock YOLO!)
Which everyone has already mentioned. The top 3 guys are rising stars in college football, and if you can snag someone like that when they're young, you do it. Frosty is obviously head and shoulders above the rest. Fuente has a longer track record than Campbell does.
I was super averse to Bielema at first. I've always kind of disliked that guy for putting so many whoopings on us. But I thought he handled his dismissal with class and he knows how to win in the Big 10, without a doubt. He's old, but he's not a bad fallback. At least it would please Run the Ball guy.
