The center and power forward positions are the only two that we are nearly certain of who will start
Sean Miller mentioned that the Arizona Wildcats were only looking to add one more player after the departure of Stanley Johnson. A day later, the Wildcats landed graduate transfer Mark Tollefsen, which means we can assume that the roster is now set for the new year.
Three things come to my mind when I think of the 2015-2016 roster. Shooting, experience, and backcourt depth. The Wildcats will no longer be called a team that "struggles to hit jump shots".
