Garnett has played with more all stars. He's had better point guards. Latrell Sprewell has made a career out of slashing. Last season, Sam and Latrell were playing out of this world. The only reason they didn't beat L.A. is because Garnett refused to take over games when Minny needed him to. He's got good defenders on the wings. Latrell and Hassell are very good defenders. , Ervin Johnson up front is a pretty decent defender, and for all of Kandi's faults, he can block some shots.
The Spurs great defense is a product of their system. Beyond Duncan and Bowen, they don't have any great defenders. They have good defenders who know their roles.
