The money made by Temple makes it seem like being a stepping stone job isn't half bad and can be a source of revenue! However, you need to be able to show you can make solid hire after solid hire. Something Cincy did for a bit and Temple seems to be doing now.
Brown seems like the best, and more logical, choice for WVU. However, If the cupboard at WVU is as bare as some have suggested, it will probably take Brown a couple years to get it going, but if he can recruit athletes to Troy capable of beating LSU and Nebraska, I would think he should be able to convince kids to come to WVU.

The guy many here were touting as HC when diaco got hired...interesting to see how things have turned out for some in that search (Diaco and Lembo specifically)...Herman, Narduzzi and Clawson have turned out ok though.
