Leach is a hell of a coach. But his teams have typically struggled against opponents with really good defenses. Since starting at Washington State, in the regular season he has cracked over 500 just once... this past year. It could be a reason more people arent looking at him. Of course the talent will be different between South Carolina and Washington State. I'm not saying he isn't building something over there, just may be a reason he may not be getting looks from other schools.
How does South Carolina feel about having a coach drunk on campus and constantly saying stuff he shouldnt? Well, Spurrier usually said stuff that made people laugh. Leach usually says stuff that people think "why the hell did he say that?"
