Pepperdine is showing defensive improvement. The Waves are giving up five fewer points per game since conference play began. They have allowed just 65.3 points during their last three games. Santa Clara ranks 300th in scoring at 65.7. The Broncos face the nation's fourth-best 3-point defense, too. 
Santa Clara, though, ranks 11th in defensive field goal percentage. Pepperdine has averaged 68 points in its last two games. The Under has cashed in seven of Santa Clara's last eight home games for 88 percent. 
So I see this total being set too high.
