GLENDALE, Ariz. — If the Chicago Bears finish the season without a loss, they will look back to that strange night in Arizona when they had a victory that was as improbable as they come.

"I have never seen anything like that," Bears quarterback Rex Grossman said. "It was unbelievable."

Six turnovers, 3 points on offense, and somehow the Bears are still without a loss after beating the shellshocked Cardinals 24-23 on Monday night.

"I have never played so bad and won a game like that," said Grossman, who threw four interceptions and fumbled the ball away twice.

Down 20-0 at halftime, Chicago returned two fumbles for touchdowns in the second half. Then Devin Hester returned a punt 83 yards for a score with 2:58 remaining to take the lead. The night ended with Neil Rackers missing a 41-yard field goal that would have been the game-winner with 53 seconds left.

"Sometimes, when you're a team of destiny, things like that happen," Chicago coach Lovie Smith said.

Matt Leinart, who threw two first-quarter touchdowns and finished 24-for-42 for 232 yards, coolly directed Arizona downfield at the finish for a chance to claim a victory that appeared to be the Cardinals' all night.

But Rackers, a Pro Bowl kicker last season who connected from 41, 28 and 29 yards earlier in the evening, missed a 41-yarder to the left with 53 seconds left for what would have been the game-winner for Arizona (1-5).

Just last week, he missed a 51-yard attempt at the finish that would have sent the game against Kansas City into overtime.

"Neil is still one of the best kickers in the league," Leinart said. "That's just life."

The Cardinals have lost five in a row after a season-opening win. Three have come at home — all in a similar excruciating fashion.

"I've seen just about everything at this point," defensive end Bertrand Berry said. "Heart-wrenching games. You know, one team doesn't deserve to lose like this. This is a good football team."

Arizona coach Dennis Green was seething. Judging by his comments, he clearly didn't believe the Bears lived up to the hype — or deserved to win.

"The Bears are who we thought they were!" he said, yelling at the top of his lungs and pounding on the podium at his postgame news conference. "Now, if you want to crown them, then crown (them)! But they are who they thought they were! And we let them off the hook!"

Green then stormed away.

Anquan Boldin caught 12 passes for 136 yards and a touchdown for the Cardinals.

Edgerrin James carried 36 times for only 55 yards, an average of 1.5 yards. It was the most carries in an NFL game by a player while averaging less than 2 yards per attempt, according to the Elias Sports Bureau.

"The way things have turned out is just unreal," James said. "This is some of the weirdest stuff I have ever seen in these past six weeks."
