Billy Donovan > Tubby Smith
and it isn't even close.
Both coached under Patino and both have a national championship.
Donovan coaches at a fairly easy school to recruit. It is bright and sunny all of the time, he also never has the pressure Tubby did at UK. Florida is a football school, but gets bball recruits because of Donovan and the whether.
MN is a football / hockey school, regardless of the recent failures. And doesn't have the nice temperatures to attract recruits. Tubby Smith, the Big 10, and the city attracts recruits to MN, plain and simple. Believe it or not, a lot of basketball players like Florida and sunny days.
