Steve Nash has to be tired of losing early in the playoffs, and the 36-year-old knows he doesn’t have too many opportunities left to win a championship.  That has been evident so far in the Suns series against the Spurs, where Nash came out very aggressive on offense and set the tone for the series by pouring 33 points and 10 assists.  Nash had more of a scorer’s mentality in that game one victory, which looked like it caught the Spurts off guard a little bit.  Nash was a little less aggressive shooting the ball in game two, but he still managed the flow of the game very nicely to lead them to another win to put them up 2-0 on the veteran Spurs.  Game three starts tonight in San Antonio, so it will be interesting to see how the experienced Spurs team performs at home.  It could be a difficult environment for the Suns, but as long as they have Nash playing the way he is they will have a great chance to go up 3-0 tonight.
