BYU could weather dry spells shooting the 3, because Mika would get to the line and knock them down. He singlehandedly stopped some potentially big runs and put other bigs on the bench with foul trouble. He was a foul magnet.
On the flip side, good programs always reload. No player should be irreplaceable. It will be interesting to see if other players step up next year. There was a weird vibe to the team last year that makes me nervous.
