Charley Rosen has ideas. One of the best involves exploiting Spurs guard Brent Barry, who is not a great defender:
In Barry's first rotation, the Suns cleared out a side for [Jim] Jackson and let him go one-on-one to great effect. But with the increasing overemphasis on screen/rolls as the game progressed, Barry had a free pass on defense since whomever he was guarding wasn't involved in the offense anyway. This turn of events is what enabled Gregg Popovich to keep Barry on the court.
