"We haven't had our team in eight or nine games," Brand said. "Now we have a team and we're building on our season."
Playing for the first time in three weeks, Cassell scored 10 points during the Clippers' decisive 17-3 fourth-quarter surge, including a 3-pointer that gave Los Angeles the lead for good at 79-77 with 9:12 to play. He sandwiched another 3-pointer between two jumpers, and Mobley added a jumper for a 91-80 Clippers lead.
Cassell had missed seven games with plantar fasciitis in his left heel before returning against the Hornets, and Mobley hyperextended his left elbow last week at Miami.
"It's about playing with confidence. It's about having that attitude. It's about bringing that swagger," Cassell said. "I'm going to bring that swagger every night. That's what it's all about.
"If we continue to do that -- have that swagger, keep our composure and just play hard -- the key to our success is how hard we play."
Desmond Mason led New Orleans with 28 points for the second straight game, picking up his first consecutive 20-point games since his final three games with Milwaukee at the end of the 2004-05 season.
It wasn't enough to prevent the Hornets from getting swept on a four-game homestand for the first time since March, when they lost three games in Oklahoma City and one in New Orleans. The last time the Hornets lost four home games in the same city was from Jan. 26 to Feb. 4, 1994 in Charlotte.
"Our mistakes are beginning to be the same things over and over again. That is the thing that is bothering me," Hornets coach Byron Scott said. "We are putting too much pressure on ourselves when the game is on the line, and we are making too many mental mistakes, too many physical mistakes."
The Hornets committed six of their 15 turnovers in the fourth quarter and shot only 33 percent in the final period.
Brand knows that feeling. Fighting through injuries to Cassell, Mobley and Corey Maggette, the Clippers gave up double-digit leads in losses to Orlando and Washington on their current six-game road trip.
"It's tough," said Brand, who finished with 18 points and 12 rebounds. "You find a way to lose."
Getting healthier, the Clippers won for the first time in 12 tries when trailing after three quarters on the road. Brand said the next step is improving on their 16-19 record and shedding questions like "Is it over?"
"I thought that was ridiculous because we haven't played with our whole unit yet," Brand said, adding: "I think we can make a run."
New Orleans led by as many as 13 in the opening minutes of the second quarter but Los Angeles cut it to 51-49 by closing the half on a 12-4 run.
Cassell tied it on Los Angeles' first possession of the second half, and the Clippers then claimed a 57-53 lead after back-to-back 3-pointers by Mobley and Cassell.
New Orleans answered with a 20-6 run that included eight points from Mason, and Chandler's spinning, left-handed layup put the Hornets up 73-63. Los Angeles then finished the third quarter on a nine-point burst to get back within one before maintaining momentum into the fourth.
- Los Angeles' Tim Thomas got a technical foul with 10:48 left in the second quarter for cursing at an official after being called for his third foul in three minutes of playing time.
- Hornets G Bobby Jackson, who missed 16 games with a cracked left rib, is expected to have an MRI exam on Tuesday to determine what is causing him back pain. He scored seven points in 10 minutes Thursday against Detroit but hasn't played in New Orleans' last two games.
- The Clippers signed G Luke Jackson, a former first-round pick out of Oregon, to a 10-day contract. He did not play.
- Attendance was 15,501, the lowest yet for a regularly scheduled game in Oklahoma City. The only lower total was 14,554 last January for a game moved from Baton Rouge, La., on short notice.
