Dirk, Josh and Jet are the biggest Spurs killers, followed by Devin at #4, then Stackhouse at #5, Damp at #6 and Diop at #7.
We gave up our fourth and seventh-most important players when it comes to the Spurs. There are going to be times when we miss Harris' speed and Diop's shotblocking, but I was pleased to see that the Mavs are still going to a to play for the Spurs and any series between our teams is going at least 6 and probably 7 games.
Here is what Tony Parker has done to the Mavs since the beginning of that playoff series two years ago: 19 points and 4 assists per game. And here is what Devin has done against the Spurs: 12 points and 3 assists per game. And maybe you're forgetting that in Game 7, Parker abused Devin: 24 points, 5 assists and 1 turnover to 2 points, 0 assists and 5 turnovers for Harris. Harris has improved offensively since that time, but the speed is still the same.
As for Diop, he's living off that Game 7 overtime against Duncan when he sat the bench the entire regulation while Timmy was gassed. The guy who banged on him all night and helped wear him down is still here. Dampier is no Duncan stopper, nobody is, but he does what one can against him as well as can be done.
