The 7-foot, 235-pound center from San Diego Cathedral Catholic announced his decision via Twitter.
McCoy gives the Rebels a hard playing center with tremendous size. He's a capable finisher around the basket, improving shooter, a capable rim protector and rebounder and a tough, physical kid.
The five-star prospect is a signature commitment for Marvin Menzies and staff in Las Vegas. McCoy should step right into UNLV and be one of the Mountain West's top players from day one.
