Kragthorpe, I feel bad for because of the health problems that he and his family have been through the last few years. But honestly that notwithstanding, he just is not a very good coach. He absolutely shite the bed then set it on fire at Louisville. Its no coincidence that Petrino won over 40 games in 4 years and took them to the BCS before Kragthorpe and Strong brought them back to double digit win seasons and the BCS after Kragthorpe. I don't really see our QBs progressing. Krag has never been a good recruiter and never will be.
He's not a head coach. He was a good coordinator and is a well respected QB coach. And he's responsible for both of the highly regarded QBs currently committed.
His head coaching failure has nothing to do with his ability to coach a QB. A first year starter progressed and improved during the year this year and Lee had his best year as a QB under him.
