Mitchell was once the Lost Boy among the five-star recruits in the class of 2010. He committed to Missouri out of Pinkston High in Dallas but was unable to enroll because of academic issues. He arrived at North Texas in January 2011 as an academic nonqualifier and wasn't eligible to play until the following December, missing the first nine games of the '11--12 season. Mitchell appeared in 23 games as a freshman, averaging 14.7 points, 10.3 rebounds and 3.0 blocks while dismissing all doubts about his rustiness. His 7' 3" wingspan, 41-inch vertical leap and feathery outside shot make him the most versatile power forward in the nation. Says Mean Green coach Tony Benford, an assistant for four years at Marquette, "Mitchell is a 10 on the athletic scale. He's better than any athlete I saw in the Big East."
Mitchell was the lone D-I player to rank in the top 20 in defensive rebounding percentage (28.8, fourth) and shot-blocking percentage (11.0, 15th) last season. Only three other players even cracked the top 50 in both categories: Kentucky's Anthony Davis (the No. 1 pick in the draft), North Carolina's John Henson (No. 14) and Norfolk State's Kyle O'Quinn (No. 49).
"He's first-round material, and if he improves—scouts want to see him show a more consistent level of effort and dominate his league [the Sun Belt Conference]—he'll go in the lottery."
