I don't doubt that he'd be able to rebuild KU and make them a contender / win the conference, I just think it'd be tough for him to do it in 3 years. They're absolute garbage and it would take a few years for Urban to build something there. Urban would have to prove his worth before he'd be able to pull 4/5 stars to Lawrence. Look at Les Miles. He's not as good of a coach as Urban, but he was incredibly successful at LSU and still had solid records when he left LSU, and he's struggled immensely so far. This quite possibly be the worst KU team in history.
