In his playoff career, Tony Parker has at least held par with, if not outplayed, Stephon Marbury, Andre Miller, Jason Kidd, Allen Iverson, Gary Payton ( in D. Fish), and Steve Nash (repeatedly).
The only point gaurd that really has Tony fits was Chauncey Billups, which was half to Detroits credit defensively and half to the fact that Tony hadn't developed a jump shot at that point. The Nets and Lakers of the past were able to contain him by focusing their concentration on him, but that is what makes the separation between stars and superstars: the ability to play through that focused attention.
Tony is a confirmed superstar at this stage now. what all the haters say, a Finals MVP makes up for a few shakey playoff years. He brought it to the biggest stage when this team needed him most, and I for one am relieved to believe that the Spurs may have a second primetime with Parker at the reigns and Duncan in his twilight.
Steve Nash can rack up all the assists he wants with a run and gun, 187-points a game system. If it came down to picking for playground ball, I would go straight for Tony Parker. After all, I always thought you were supposed to pick the best guys first. The guys that are going to win you games.
