Sadly, I don't see it. Soon to be 24 year old rookie 2nd rd draft picks don't often materialize into superstars.
Tell it to Manu Ginobli. There have been a number of second round picks who became all stars. Does it really matter all that much that K-Jo is 24 as a rookie instead of 22, like Mike Finley, or Stephen Jackson. How about Bruce Bowen, not a superstar, or even an all star, but a very solid player who stuck in the league at age 25 after not being drafted.
It doesn't matter where you are picked or how old you may be. IF K-Jo has NBA skills and a good motor, he'll play in the NBA. I think he does, by the way, and would like to see him get a few minutes and maybe prove himself, like the other Ainge second round picks - Gomes, Powe, and BBD.
