1) Cunningham: We saw flashes last year when he was pressed into duty, but he looks like he'll be a player. He seems to have added some ability to put the ball on the floor and attack the hoop which is absolutely essential if he's going to pick up spot minutes at the three, and it will keep defenses honest, being a credible double threat to either pick and pop, or drive a little.
2) Johnson: I like his willingness to defend and although I think he's got some bad habits that will have to be corrected (the goddamn jump pass!) he seems to have an NBA body, NBA quickness and I just like his sense of pace and control ... he definitely seems to have a role-player's mentaility which is probably what you are looking for in a backup point guard. A couple of knocks though. His jumper outside of fifteen feet looks to be pretty suspect, and even though his court vision looks to be OK, he's got a lot of work to do if he's going to be running an offense.
3) ???: I'm not sure I can put Williams here based on the fact that I've never actually seen him play a single minute, and I don't feel comfortable putting Babbitt or Pendergraph here either. But if pressed I'd probably guess Williams based on his freak athleticism and the fact that he supposedly has some nice upside, a close second would probably be Babbitt. I can't tell if the achilles thing has slowed him down, and even though I'm dubious about his pro potential, he did show some nice flashes of creativity, seems to have a good basketball IQ, and he finally stroked it with confidence in the second half last night which was good to see. JP on the other hand is a stiff; nice guy, hustles, rebounds OK, has a nasty streak, but holy balls is he clumsy and rigid on offense, and not really all that effective a defender in the post -- he made Patrick O'Bryant look like a polished low post scorer.
