Spurs are going to squeak out a very close game. Nowitzki is going to have the basketball gods behind him (as always). Butler and Marion are going to have subpar games. Kidd is going to play like the scrub shooter he is and have a bad shooting night. JJ barea is going to play good and Jason Terry is going to come back from a subpar game to contribute.
Duncan is going to play similar to how he played in Game one. Ginobili is going to will this team to victory. Parker is going to play well. Jefferson is going to step up (very big if). McDyess is going to bring it. The rest of the Spurs (not including Mason) will play a very good defensive game.
However, note that if the refs call the way they called game one... good defensive is always negated by bad officiating. This might make it seemingly impossible to beat the Mavs.
Nonetheless, Spurs win.
96-93
