The big man has left the building. Since shoulder surgery ended Central Florida's ultra-rim-protecting, 7-foot-6 center Tacko Fall's season, the Knights have allowed an average of 10 points more per game than their season norm of 61.3. Opponents can now see the hoop and are filling it up. UCF covered just once in those games. The visitors welcome back guard B.J. Taylor (12.9 ppg), but a persistent ankle injury could impede him. Knights games have gone Under in eight of the last 10, and they have too little offensive pop to make up for Fall's missing defense.
