There's definitely ways to be an affective 3 with out ball handling ability, I mean just look at Shawn Marion. But if Derrick Williams wants to truly reach his full potential, he will need to develop that part of his game.
Not going to take a side or anything (since I don't feel particularly well-informed about Derrick Williams' game and upside to have my own opinion yet), but just thought this list needed some adjusting. That list seems a little ... older. I don't even think Melo belongs on the list because from the few 2003 scouting reports I was able to find, they had him pegged as a SF first (http://sportsillustrated.cnn.com/basketball/nba/2003/draft/news/2003/05/20/mandel_draft/ : "He runs the floor like a gazelle, equally capable of spotting up over a defender or slicing to the hoop. He's an excellent rebounder and solid ball handler, and when defenses collapse on him, he has the court sense and passing ability to find the open man."). I could be mistaken, but I don't think Melo was ever thought of as a tweener. He did play on the team with a classic tweener in Hakim Warrick though.
DraftExpress has his potential as Michael Beasley w/ perfect intangibles.. Beasley is a VERY good offensive presence.. If this is true at all about Williams I'd draft him without hesitation.. I have no doubt the rockets will either work him out or observe one of his workouts to determine his ability to play sf.. if he shows any sort of real ball-handling skills I dont see any reason why they wouldnt make the #2 pick a top priority..

I like to think of it as Irving / Williams = Paul / Marvin Williams. Of course the one stat that argues against this is the fact that Derrick Williams shot a maddening 57% from the 3 this year (42 of 74 so not too small a sample size either). I do think that his game against Duke has elevated his stock above where it should be though, and that Kanter is going to be the better player.
