BYU attempts a 3 pointer on 36.6 of all FGA. The NCAA average is 35.3%. BYU attempts an average of 64.4 FGA a game, so if they "ONLY" attempted an NCAA average percentage of 3 pointers, they'd attempt only 22.7 threes a game instead of 23.6. A grand difference of 0.9 attempts per game.

Furthermore, BYU makes 38.1% of their 3s, which is the 38th best percentage in the nation (of 351 teams). So unless you're making a generalized statement about college basketball and its willingness to live and die by the three, BYU is not appreciably any more reliant on the shot than your average team and in actual fact is more effective with it than the overwhelming majority of teams.
