The Spurs have rolled into the All-Star Break with a 42-12 (77.8%) record, which has them in first place in the Western Conference, 2.5 games up on the Thunder.  Here is a look at the players who made the biggest impacts for the Spurs in the first half of the 2012-13 season:

Team MVP:  Tony Parker - 30-year old point guard Tony Parker keeps rolling along for the Spurs as he just seems to keep getting better.  He has played in 51 games (all starts) for the Spurs so far this year and he is averaging 32.9 minutes, 20.8 points, 3.0 rebounds and 7.6 assists per game.  He is shooting an amazing 53.6% from the floor so far this year, which is outstanding for any player, but especially a guard.

Biggest Surprise:  Tiago Splitter - 28-year old center Tiago Splitter has taken his game to a new level so far in 2012-13.  Splitter has played in 54 games (32 starts) for the Spurs so far this year and he is averaging 23.8 minutes, 10.6 points, 5.9 rebounds and 1.4 assists per game.  Splitter is shooting a rock solid 59% from the floor so far this year.  The Spurs hope that Splitter keeps rolling in the second half of the season.

Biggest Disappointment:  Stephen Jackson - 34-year old small forward Stephen Jackson is having a horrible year for the Spurs.  He has played in 36 games (3 starts) for the Spurs so far this year and he is averaging 20.9 minutes, 6.6 points, 3.0 rebounds and 1.4 assists per game.  He is only shooting 37.5% from the floor, 25.9% from three point range and 69.6% from the free throw line so far this year.

Sure, the Spurs had their eyes on winning the NBA Championship, but they still had a solid year despite falling a tad short of their goal. The Spurs finished up with a 50-16 (71.4%) record during the regular season and they were 10-4 (71.4%) in the post-season. Here is a look at the players who made the biggest impact for the Spurs in 2011-12:

Team MVP: Tony Parker - 30-year old point guard Tony Parker was outstanding for the Spurs in 2011-12. He played in 60 games (all starts) for the Spurs last year and he averaged 32.1 minutes, 18.3 points, 2.9 rebounds, 7.7 assists and 1.0 steal per game. Parker made everyone on his team better in 2011-12.

Biggest Surprise: Daniel Green - 24-year old SG Daniel Green rose up from the ashes for the Spurs this year. Green played in 66 games (38 starts) for the Spurs last year and he averaged 23.1 minutes, 9.1 points, 3.5 rebounds and 1.3 assists per game. Look for his rise to continue next season for the Spurs.

Biggest Disappointment: James Anderson - 23-year old SG James Anderson was a first round pick in the 2010 NBA Draft by the Spurs, so they were expecting big things out of him. But, he played pretty lousy last year for the Spurs. Anderson played in 51 games (2 starts) for the Spurs last year and he averaged 11.8 minutes, 3.7 points, 1.5 rebounds and 0.8 assists per game on a pathetic 37.9% shooting from the floor.
