LOS ANGELES, SEPT. 30 -- Maybe the Los Angeles Raiders really are the worst unbeaten team in the NFL, if there is such a thing.

They won't argue with you. They probably won't listen to you. The Raiders only allow themselves to be judged by themselves, which is why they were so happy after today's 24-10 victory over the Chicago Bears.

"The respect for us is right here, in this locker room," said Los Angeles running back Greg Bell. "There's no sense in trying to convince you guys. But there's four teams we beat that respect us, I guarantee you that."

The Bears were added to that list before a season-high crowd of 80,156 (with the big crowd came some problems: 31 arrests and 88 ejections in a campaign against stadium violence at the Los Angeles Memorial Coliseum), as the Raiders met with their latest challenge more impressively than their previous three.

In winning this battle of unbeatens, the Raiders improved to 9-0 at home under Coach Art Shell.

"I've read {and} heard things about us being the worst 2-0 and 3-0 team in the league," Shell said. "It doesn't matter what anybody else thinks. . . . As long as we do what we think, nothing else matters. This is a good football team, and nobody can tell us different."

With two scoring runs from Marcus Allen and a fumble recovery for a touchdown by Greg Townsend, Los Angeles (4-0) did something it hadn't done in 1990 -- score more than 20 points.

As a bonus, those points came against a Chicago defense that previously allowed only 29 points and two touchdowns.

The sudden dose of offense served as a long-awaited complement to the Los Angeles defense, which entered the game having allowed an NFL-low 25 points and one touchdown.

Led by Townsend and Aaron Wallace, the Raiders defense held the Bears (3-1) to 229 yards and 11 first downs, and sacked Chicago quarterbacks Jim Harbaugh and Mike Tomczak six times for losses totaling 66 yards.

"We played very poorly today in all areas," Chicago Coach Mike Ditka said. "We got beat by a good football team, but that does not compensate for the fact that we played very poorly."

Los Angeles outgained Chicago, 257-170, in the first half as it built a 17-10 lead. After a scoreless third quarter, the Raiders scored their final points on Allen's second touchdown run -- a three-yard sweep with 9:11 remaining.

The chances for a touchdown on that drive appeared in danger until former Redskins quarterback Jay Schroeder, on third and nine from the Chicago 43, completed a 20-yard pass to Mervyn Fernandez.

Allen scored six plays later, following a block from running back Steve Smith of DeMatha High School.

Again, Schroeder was not called upon to throw often. He entered the game ranked fourth among AFC passers in efficiency, and continued his success rate today by completing eight of 15 passes -- including a 59-yarder to Willie Gault in the first quarter that set up Allen's first touchdown -- for 178 yards.

Schroeder did not throw for a touchdown, but didn't throw an interception, either, which is all Shell has asked.

"We threw the ball and opened it up a little, and when we wanted to go back to the run, we were able to do it," Schroeder said. "I think everybody feels good about what we're doing."

The Raiders defense may have made the game's key play. On a third-down play, defensive end Townsend and linebacker Wallace chased Harbaugh to the Chicago 3, where Wallace knocked the ball loose.

Wallace was credited with a 20-yard sack; Townsend, who recovered the ball at the 1 and crawled into the end zone, scored his fourth career touchdown to make it 17-7.

The play of Townsend and Wallace, among others, forced the Bears to throw more. But Chicago, which received limited effectiveness from running back Neal Anderson (sore ribs), had trouble running and passing.

"I'm giving our offense credit today," Townsend said. "We opened up the scoring which made them open up their offense. That's what we always want teams to do. We want them to have to throw the ball so we can get something done up front."

"We only put 10 points on the board. That pretty well sums it up," said Harbaugh. "I've got to make a few more plays, get us into scoring position and get some touchdowns."

Harbaugh, who completed only five of 16 passes in last week's victory over Minnesota, produced an 80-yard score on his first pass today, connnecting with Dennis Gentry down the right sideline to tie the game at 7 in the first quarter.

Los Angeles regained the lead on its next possession as Schroeder (six for 10 in the half for 151 yards) completed a 27-yarder to Gault that set up Jeff Jaeger's 27-yard field goal.

Schroeder nearly threw a touchdown pass on the previous play but Fernandez was unable to hold on to the ball in the end zone.

Each time Los Angeles has opened a season with four victories, it made the playoffs. The last time the Raiders did it, in 1983, they went on to defeat the Washington Redskins in Super Bowl XVIII, 38-9.

"It tells us we've got a real good football team," Schroeder said of the win. "It also tells us we can't relax."
