1) Run-and-Gun this time will be the weakness of the aging Spurs, too slow.
2) Too much offensive weapons for the Suns than the Spurs. Nash has still the MVP instinct that he wants to show to everybody that his passing may become a legend.
3) Amar'e Stoudemire will pound Tim Duncan inside in the PF match-ups. Nash will definitely school George Hill and J-Rich and Ginobili may have their nights as well.
4) Too much 3-pt shooters from the Suns that will carry them over the Spurs.
