Well, The Spurs should have taught them a neat lesson that speed alone cant get them far. The Spurs can set their halfcourt offense with ease, they deliberately slowed the tempo to their advantage, and since they were a lot bigger, controlled the boards and somehow limited the Suns transition points. The key to the Suns' running attack is securing the defensive rebound and make the quick outlet passes.
just my two cents...who knows maybe the next time, they can really prove they can win running away from the Spurs.
