Everybody should be skeptical about the Spurs start..
While the Spurs can get better if Splitter is acclimated to the lineup, since he would make the defense better and give the Spurs a better balance of offense/defense, they will still have to deal with the inevitable decline in shooting..
Bonner: 69% from 3 on almost 4 attempts per game(absolutely disgusting numbers, no chance of continuing)..
Anderson: 50% from 3 on 3 attempts per game..
Jefferson: 46% from 3 on 4 attempts per game..
Neal: 43% from 3 on 3 attempts per game..
Manu: 40% from 3 on 7 attempts per game..
They obviously won't sustain that, it's pretty much impossible..
So what it comes down to: Will Splitter's potential addition to the rotation + Manu and Duncan going harder(more aggressive, attacking the paint) in the 2nd half of the season/playoffs negate the inevitable and eventual drop-off in the Spurs shooting %s?..
Then you have to factor in the chance of injury, which is always a concern, however, you can say that about most teams..
