Brett Brown was the Spurs player development coach from 2002-2013 and won four titles with them. I trust him with developing any projects we bring in.
With that said, Embiid and Lavine wouldn't exactly excite me as our tanking prize. I'd prefer Exum and Gordon if we're going the developmental route.
The difference between D-Will and Gordon is that Williams wants to be a small forward and jack up a bunch of threes trying to cross guys on the perimeter. He's basically an "I get buckets and do nothing else" type of player. Gordon wants to be a power forward, can guard basically any position, wants to do the dirty work, has a tremendous basketball IQ, hard worker, gym rat, makes good decisions with the ball and is a great passer.
