"We know we're a handful on the offensive end," Barnes said. "If we can start controlling the defensive end, that's when we're really going to start winning games and making an imprint in this league. We have the talent to do it. We have the athleticism to do it. It's just the heart and hunger to do it."
Jackson's injury didn't muster any sympathy from Paul during or after the game.
"Injuries happen," he said. "We're without Chauncey (Billups, left Achilles rehab) and Grant (Hill, right knee bone bruise)."
Paul's jumper gave the Clippers a 34-33 lead with 5:31 left in the first half that they extended to 45-36 on Paul's 22-foot jumper.
Danny Green's 3-pointer pulled the Spurs to 67-63 with 1:29 remaining in the third, but Paul responded again with another jumper on the ensuing possession.
