Wilson averaged 11.8 points and 3.9 rebounds as a freshman at Mount St. Mary's last season. He had considered both Miami and Auburn, but tweeted his decision Thursday night, saying The U was his "next chapter."
Wilson must sit out a season under NCAA transfer rules. He has three years of eligibility remaining.
"Miles comes to the U after a very successful year at Mount St. Mary's, where he helped them reach the NCAA tournament," UM coach Jim Larranaga said in a statement released Friday. "Miles has the size, length and athletic ability to be an outstanding defender; in addition, he has the shooting and ball handling skills to be a real threat at the offensive end."
