I've been thinking about it alot lately and here is why Mason wins it all:
Campbell has been hitting 50% of his 3's this tornament
defensively, Mason is really good at getting in passing lanes and at not allowing any player to establish post position
Mason always spreads the ball around to everybody on offense
Lewis and Thomas always create fouls and get their opponents in foul trouble
their starters have great endurance and are on the floor for the large marity of the game, so while their opponents have back-ups in Mason's starters will have a field day
most of all Mason will just outplay you, they always play hard
