Davidson has switched its primary defense playing more zone. It has paid off as the Wildcats have held nine of their last 10 foes to 70 or fewer points. The Wildcats have moved up to No. 2 in defensive efficiency in the Atlantic 10 Conference. The No. 1 team in the conference in terms of defensive efficiency? It's Rhode Island. The Rams figure to be rusty, too, having not played in a week. So look for points to be harder to come by than the oddsmaker believes.
