Before Kentucky became involved with Matthews I can recall it was known Ohio State, who recruited him hard, viewed him as an "elite defender". I remember it was thought he was on par with David Lighty in that area and Thad hoped he would fill that same role for Ohio State. If Charles has similar skill as Lighty did, defensively, then the UM staff has a really nice piece to work with.
I'm curious to see Matthews on court next season for Michigan. Saw him a little when he wore Kentucky blue but not enough to comprehend his real talent on defense or offense.
