A Bears team that wasn't supposed to accomplish much won its fourth straight game Sunday at a stadium they weren't originally scheduled to play in with contributions from players who weren't supposed to be here.

Robbie Gould's 28-yard field goal with six seconds left put the frame around an imperfect 20-17 victory over New Orleans, playing its second game at LSU's Tiger Stadium after Hurricane Katrina damaged the Louisiana Superdome.

As Gould high-fived fans who probably had no idea he was working for a construction company two months ago, others chanted the name of Cedric Benson, who combined with Adrian Peterson to relieve the injured Thomas Jones with aplomb.

Ten feet away, Muhsin Muhammad pointed a finger skyward, either an acknowledgment to some higher power or a nod to the huge 22-yard pass he caught from Kyle Orton to set up Gould's heroics.

And linebacker Hunter Hillenmeyer conducted an interview for two TV stations simultaneously, which seemed fitting since he was everywhere on defense.

This improbable Bears season has come to this: You can't take two steps in the postgame locker room without running into a player who contributed.

"You never know who's going to step up and make a play," linebacker Brian Urlacher said. "It seems like every week it's somebody new. We have a lot of good players on this team.

"People can call it winning ugly. I've never seen an ugly win. I've seen ugly losses, but never an ugly win. A win is a win."

Indeed, the Bears are so flush with victory that they're now in the practice of grading them. Player after player and coach after coach talked about not playing well, just in case defensive coordinator Ron Rivera's blistering halftime rebuke hadn't reminded his unit.

But the Bears' first four-game winning streak since the end of 2001—their last playoff team—opened a two-game lead in the NFC North and reminded everyone of one of the oldest adages in sports.

"Good football teams find a way to win when you don't play your best ball," coach Lovie Smith said. "That's what happened."

The Bears now prepare for back-to-back home games with as much confidence as momentum, the game-winning drive absolving the sins of the offense and near second-half domination doing the same for the defense.

A three-and-out Saints possession ended when Alex Brown slowed Aaron Stecker and Lance Briggs wrapped him up for a 1-yard loss, forcing New Orleans to punt.

With 4 minutes 8 seconds left and a game mostly to forget behind him, Orton and the offense went to work. Benson burst off left end for 27 yards, then picked up a tough first down on a 2-yard gain. Peterson, who had scored a go-ahead third-quarter touchdown, ran for 6 yards.

"Our running backs are definitely the strongest part of our offense," Muhammad said. "If one guy goes down, we have another guy who can go in there. If that guy goes down, we've got another. We have essentially three starters."

They set up Orton—on third-and-5 from the Saints' 32—to loft a perfect touch pass to Muhammad, who beat Mike McKenzie. Making his eighth straight start, a franchise record for rookie quarterbacks, Orton wasn't great with two interceptions, a lost fumble and a 43.3 passer rating.

"But the thing I like about Kyle is that even though he doesn't make every play, he's going to stand in there and deliver the next ball like he never knew what happened on the last play," Muhammad said.

Three rushes later, Gould drilled the game-winner after making a 35-yarder and missing a 47-yarder earlier.

Such an outcome seemed unlikely early when Stecker returned the opening kickoff 45 yards to the Saints' 48 and Antowain Smith ripped off a 42-yard run to the Bears' 3. The defense stiffened to surrender only a 22-yard John Carney field goal.
