Brad Stevens left for the NBA! Had he stayed, Butler would still be a power. If Marshall stays at WSU, they will be good. UMass and Memphis would be awesome if Calipari was still there. Xavier would be great if Sean Miller stayed. Army would be great if Coach K stayed.
UConn is unique in that it is sort of a destination job, especially for Ollie, not a stepping stone like Xavier or Umass. He will have a title/final four and unparalleled success to lure players. Being likable doesn't hurt, either.
What if they upgrade facilities or get into a power conference? What if things realign in 15 years and Syracuse is left out?
