They are going to miss Underwood the most. That guy can coach. Not sure he can recruit since he seems to leave when the talent leaves but he can coach and motivate.
They can be the most talented team in the conference (not saying they are) but without a competent coach they will not be very good. We had some talented teams that didn't amount to much because the guys on the sideline, who wear a coat and tie, weren't up to snuff.
