I’m going with Williams, but my guess is that Earlington is further along than Roberts.
I voted for Earlington, who scores a point for every two minutes he plays. That makes him potentially a 20 point scorer. Roberts averages a rebound and a block at three minutes a game, which averages to 13 rebounds and blocks per 40 minutes, which is Nate Thurmond territory. Probably it's too early to nominate him for the college BB HOF, but I have him penciled in.
