As for the hire, stylistically it's a solid fit with Wisky playing smashmouth get after you FB. He's not a bad coach, time will tell how good. I also suspect he isn't so dumb as to bring a bunch of people here to recruit areas they're not familiar with. I suspect he'll bring 1-to-3 coaches with him, perhaps a coordinator, and fill in the rest with people familiar with the landscape in the southeast.
I'm sure people were saying similar things about Coach Saban when LSU hired him. Either you can coach or you can't, period. Sometimes it's just not a good fit, but that doesn't appear to be the case.
