Auburn is used to high-scoring SEC opponents who can play fast. That's certainly not Yale. The Bulldogs are a well-coached Ivy League team that is going to try to frustrate Auburn by playing at their usual slow tempo. They ranked in the top-30 in having the slowest possession time. 

Yale earned its way to the NCAA Tournament by nipping Brown, 62-61, in the Ivy League Conference Tournament final. The Bulldogs like to score inside. That's going to be problematic against Auburn, though, because the Tigers have the 16th-best shot blocker in the country in Johni Broome. 

The Tigers' strength is offensive rebounding. Yale, however, doesn't foul much and ranks in the top-15 in defensive rebounding. 
So this matchup sets up for an Under.
