What Tony Parker has is luck. If he had ended up on any number of other teams, we may not have seen him develop nearly so well as he has. He has exceptional quickness, but his court vision was never going to get him much playing time. He needed a patient coach and that is what he got, on a team with enough addtional firepower where his flaws were not tantamount to team failure.
As for working out in the off-season, Sacramento center, Brad Miller, of all people, has developed a physique. I know, you wish you had been sitting down before reading that, but it is true. He has taken to personal training to the point where his personal trainer goes everywhere with him so he won't miss a session. He has lost 25 pounds from last season and is down to about 245 pounds now, and has muscle definition.
Says something about the Kings' management drafting a 7 foot offensive center in this year's draft to motivate the current center, I have to say.
