BYU might have a good game here and there , but they are not close to the same team without Nixon. BYU is really good with Nixon. Otherwise, not so much.
Nixon is a complete, legit D-1 player. Very athletic, excellent shooter, defender, rebounder, motor, and hands. He wins nearly every 50-50 ball. Plus, he is very smart, unselfish, uplifts his teammates, and he leads.
He'll make money playing somewhere next year.
Without Nixon, BYU goes with a 7-man rotation.
