Dude has won the conference that we haven't been able to win (when it was arguably a tougher conference), won 11 and 12 games in a season, beat UF in a bowl, I could go on.
He struggled at Texas but he has won on a bigger stage than ours, so yeah, I rate him higher than Willie.
All that being said, I didn't want Willie to leave but I think this is ultimately a step-up...
Only time will tell though.
