How much have the Spurs left ?

The San Antonio Spurs had a very slow start in the 08/09 season by losing 4 of there first 5 games. The Spurs used to be a powerhouse in the west in the past years, but i wonder if they are still able to dominate the same way in the new season. With Manu still sitting on the sideline after his operation, they don’t really have anyone coming of the bench helping the starters to score. Unfortunately Tony Parker rolled his ankle and is also out for four weeks. It really is a bad start for the Spurs and I’m wondering if they are deep enough to handle the loss of there two stars. I know they have 77 games left to play, but the western conference seams to be even stronger and tougher than last season so I wonder if they have enough left to get a spot in the playoffs this year.
