I'm sure he did (he also had Tatum over Harden, fwiw), but really, I think if I were Boston I would trade Tatum for Durant right now. You decimate the best team in the league and you pretty much cement yourself as the favorite to win the title this year. Sure Durant might walk, but you're probably going to have a ring for your trouble.
Tatum is a good prospect, he's a good player now and hes going to continue to be really good. But I'm not sure he's ever going to be one of the super elite level players in the league.
