You folks don't get it, Parker has flourished under Pop's system. Yes, he's become a type of JoJo White, all around great combo-guard player but within a system, not as as solo artist. Rondo, on the other hand, is attempting to become a stats fodder, much like Stockton but w/o an outside shot, to compliment his passing game. If Rondo had played under Pops, the C's today, would be the most unstoppable squad in the league. Rondo would hit his jumpers, every single time, if a team played 5-on-4 against him. Thus, opponents would never be able to adjust their defenses against a team lead by Rondo.
And I agree on the whole Nash, not being worthy of dual MVPs. He's another rack-up-the-assists, but no overall dramatic success as a team player type of person. Nash would only win a title, on a team with another Olajuwon type of player.
With all of the above stated, it's still not clear that the Spurs would win, this time around either, unless Parker really dons the cloak and becomes Superman for his team. Neither Duncan nor Ginobili have that youthful zeal to close out the big games, in these latter years. The remaining Spurs, though decent role players, are not all stars.
If the Spurs win this year, it's because of Pop's game management, not because Parker, Ginobili, nor Duncan are a youthful big three of the pre-2008 era.
