Chucked up a bunch of 3s, failed to take the ball to the hoop (which Ole Miss did well), made some poor decisions inc
two really bad TOs by Demin and Richie (but there were others), and Ole Miss simply played better defense. And a poor finish to regulation with a questionable final possession to win it
Refs seemed a bit inconsistent, but that didn't cost BYU the game. BYU cost themselves the game.
