This is espn insider info from Ford, so I'll only excerpt a portion:
"What I saw Tuesday and Wednesday really impressed me. He's long, explosive athletically, very quick laterally and made a lot of very good decisions with the ball in three-on-three play. His jump shot is still coming along but the rest of the game looked to be there. The NBA loves big point guards and I think Lee will ultimately be a point guard in the league. I could see him sneaking into the first round and possibly even challenging Darius Morris. Morris is more of a pure point, but Lee is a significantly better athlete."
Additionally, Alex Kennedy of Hoopsworld thinks Lee has emerged as a 1st rd. prospect. One caveat there: Kennedy had glowing things to say about everyone at the camp, so take that with a grain of salt.
