Depends on if you're requiring a title to "be the best", because I'd certainly say Kelvin Sampson is one of the best in the game right now. Dude wins, gets his teams to advance in the tournament. Just imagine if he were at a spot that was more of a lure for big time recruits AND had more NIL bags. His teams compete, guard, and play a hard-nosed style.
Sure would hate to see people hold the Cal St. Peter's loss against Cal, but give Rick a pass for having the best team in their conference and not winning the conference tournament.
He needs to win more games in March, but right now there's A LOT of momentum with Musselman at Arkansas
