New Mexico State plays at a slow tempo. The Aggies aren't likely to speed things up either as a mid-sized road 'dog here. The Under has cashed 23 of the last 31 times New Mexico State has been an underdog. 

Washington State is off a buzzer-beater, 77-74, home loss to South Dakota State this past Saturday. Now the Cougars go against a much slower team. 

Both coaches are defensive-minded and the teams are strong on the defensive boards. 
So I'm expecting an Under.
