T.J. Ford scored 16 points and had 14 assists in his first game after cervical spine surgery cost him all of last season. Australia's Andrew Bogut, the NBA's No. 1 draft pick who was college player of the year at Utah last season, started for the Bucks and added 13 points and nine rebounds.
Allen Iverson scored 35 points and had nine assists, and Chris Webber added 32 points and grabbed 14 rebounds for the Sixers.
The loss spoiled the return of Maurice Cheeks in his Philadelphia coaching debut. One of the most popular players in franchise history, Cheeks has a retired No. 10 jersey and a 1983 championship banner hanging in the rafters.
Hornets 93, Kings 67
At Oklahoma City, J.R. Smith scored 19 points and had two electrifying dunks as New Orleans beat Sacramento to mark the first of 35 Hornets home games in Oklahoma City.
The celebration began with a street party outside the Ford Center, then got even more lively inside the sold-out arena as the Hornets, 18-64 last season, beat a Kings team expected to contend.
P.J. Brown finished with 20 points and 10 rebounds, Speedy Claxton added 17 and Chris Paul, the team's No. 1 pick in this year's draft, added 13.
Peja Stojakovic scored 18 and Shareef Abdur-Rahim added 14 for the Kings.
Mavericks 111, Suns 108, 2 OT
At Phoenix, Dirk Nowitzki scored 28 points and grabbed 15 rebounds and Dallas erased a 17-point fourth-quarter deficit to beat Phoenix.
The late-starting season-opener Tuesday ended just after midnight, local time.
Nowitzki sank a pair of long jumpers and Keith Van Horn made a 3-pointer in the second overtime. After Van Horn made one of two free throws with 23.7 seconds to play, Steve Nash missed what would have been a game-tying 3-pointer at the final buzzer.
Jason Terry added 23 points for Dallas, including the game-tying layup at the end of the first overtime. Josh Howard added 16 points and 11 rebounds. Van Horn scored 15 and Marquis Daniels 13.
Nash scored 30, the same he averaged against his former Dallas team in last season's Western Conference semifinals.
Atlanta Hawks center Jason Collier died from a sudden heart rhythm disturbance caused by an abnormally enlarged heart, an autopsy showed.
The state of Georgia's chief medical examiner, Dr. Kris Sperry, said Tuesday his testing showed that electrocardiograms administered to Collier in 2003 and this year showed "some indication of electrical abnormalities."
"Looking at them now, and in retrospect in knowing what's going on with his heart, the abnormalities may have been associated with what we found in examining his heart," Sperry said.
He said that he had no evidence that the 28-year-old Collier was informed there was anything wrong with his heart. Collier's wife said he had never been told of a reason for concern, Sperry said.
Collier was with the Hawks for two years after spending three years with the Houston Rockets.
