Spurs in 6. The Spurs always bring their best Game in the Playoffs. Parker will mop the floor with Kid, and Duncan and Dirk will occupy each other pretty well, but Duncan has always been better than Dirk. With guys like Mason, Finley and even the surprising Udoka playing their roles, add Homecourt Advantage and the experience of Popovich and the Spurs, and we are going to win the Series.
The only way the Mavs have a real shot is if Terry goes crazy and has MVP Performances, but with the Spurs A+ Defense, that's not going to happen.
