AUBURN HILLS, Mich., Nov. 6 (Ticker) -- Rasheed Wallace and the Detroit Pistons were too big for Allen Iverson and the Philadelphia 76ers.

Wallace scored 12 of his 16 points in a six-minute span of the third quarter as the Pistons used a dominant performance by their frontcourt to overwhelm the 76ers, 99-91.

Antonio McDyess had 12 points, nine rebounds and five blocks and Ben Wallace added 11, 16 and five for the Pistons, who held a 50-41 advantage on the glass, blocked 13 shots and totally controlled the interior.

The smallish Sixers were overmatched at every frontcourt position, especially with center Samuel Dalembert sidelined by a right hamstring strain. They were pushed around inside and settled for perimeter shots.

"It's a nightmare," Iverson said. "We get the ball in close and it comes right back at you, but you have to keep trying."

Point guard Chauncey Billups, who led the Pistons with 20 points and 10 assists, knows his team's frontcourt presents problems for almost every opponent.

"We usually have an advantage with our front line because it's big, it's athletic and it's mobile," Billups said. "We try to take advantage of their length. Rasheed and Ben and Tayshaun (Prince) have the ability to stay in front of guys and contest shots. They did a great job tonight."

"We've got a big front line -- everybody's 6-10 and up," McDyess said. "Ben's 6-9, but he plays like he's 7-foot. He plays the biggest on the team. It's going to be fun because we can just keep bringing them in and out."

Iverson scored 31 points on 12-of-19 shooting. But he did not get much help as the rest of Philadelphia's starters combined for 30 points.

"We have to establish a low-post presence and that's a tough team to do that against because they're so much bigger than we are," Sixers coach Jim O'Brien said. "Allen can't be expected to always carry the load."

Quiet in the first half, Rasheed Wallace helped the Pistons widen a 53-46 halftime lead. He made 1-of-2 free throws, a three-point play and a 3-pointer to push the advantage to 60-48.

Rasheed Wallace added another basket and 3-pointer to make it 68-52 with 6:45 left in the third quarter, and the Pistons led by double digits until the final seconds.

Ben Wallace was controlled the defensive end with his rebounding and shot-blocking. He got some help from McDyess, who had struggled in his first two games with his new club.

"I wasn't looking for shots," McDyess said. "I was just trying to play defense. I'm glad I was able to contribute more tonight than I did the first two games."

Assistant Gar Heard, who is filling while coach Larry Brown recovers from hip surgery, said he changed his bench rotation after the reserves scored only six points in Friday's loss at Toronto.

"We tried to get Antonio and Carlos Delfino in with some of our starters so they don't feel as though they have to carry the load themselves," Heard said. "I thought it worked out well. We cut down our rotation a little bit and went with eight or nine guys. That's the way we have to play until they get used to each other."

"Sometimes it's easier to get going with the starters, and then when he throws the rest of the bench players in there, you've already gotten started," McDyess said.

Iverson wasn't the factor in the second half that he was before halftime, when he scored 23 points. Philadelphia shot under 39 percent (31-of-80).

"They paid a lot more attention to me in the second half, so I did what a point guard is supposed to do, look for the open man," said Iverson, who had five assists. "We just didn't knock down our shots."
