Not seeing the star potential in Johnson. I heard all about him on this board as somebody we had to have and then watched a couple of games. He seems to be a good defender, but super-passive on offense and not exactly engaged on that end (for a supposed top-end talent). Smart was also seen as a defense-first guy, but you could tell he had those leadership skills that could not be taught.
On another note, I would definitely use James Young to move up in the draft for a better SF (including Johnson, funny enough). People talk about KO being passive and weak, but at least he helps control the game when he is in, Young has a LOT to learn. I am hoping he wasn't just hyped up because he had a good dunk during March Madness.
