CHICAGO -- Keyshawn Johnson was the next to last Tampa Bay Buccaneer to leave the locker room because he wanted to answer all the questions. The Bucs lost to the Bears 27-3 and looked lost as a team most of the game.

One of the key plays, though, involved Johnson, who turned a 10-yard route into a 47-yard gain but fumbled when Bears cornerback R.W. McQuarters brought him down at the Bears' 8 with a low tackle and cornerback Walt Harris stripped the ball from behind.

"Crap happens," Johnson said. "I'm not going to quit playing football because I fumbled."

	Brad Johnson completed just 19 of 40 passes for 191 yards and two interceptions.

And Bucs quarterback Brad Johnson isn't going to stop quick-throwing the ball to Keyshawn, who has 100 catches in 13 games. That stat is quite hollow, though. Throwing the football to Johnson is about all the Buccaneers can do these days. Warrick Dunn and Mike Alstott combined for a worthless 50 yards rushing on 17 carries. Karl Williams was the only other wide receiver to catch a pass and he had two receptions for 18 yards.

Keyshawn had seven catches for 119 yards, exactly 50 percent of the Bucs' output in a loss that only increased the rumors that coach Tony Dungy's job is in jeopardy. The Bucs fell to 7-6 and their only hope of making the playoffs is to get the sixth and last berth in the NFC.

As Johnson left the locker room discussing the team's problems, he said, "This is bigger than Keyshawn, trust me."

More than ever, the problems point to the schemes of offensive coordinator Clyde Christensen and the poor blocking on Chris Foerster's offensive line. Dungy is a head coach who always fights for his assistants. Finishing the season with three home games, the Bucs could still make the playoffs at 10-6, but something has to change on offense.

It looks horrible.

Johnson the quarterback is doing exactly what he was expected to do after being given a five-year, $28 million contract. He's getting the ball to Johnson the wide receiver. What's happened to the other players on offense? Don't they want the damn ball?

Dungy deactivated Reidel Anthony even though he was healthy. Anthony has 13 catches for 162 yards and isn't even a threat enough to wear a uniform these days. Jacquez Green started but didn't catch a pass. Williams, who has only 20 catches this season and no touchdowns, was more active.

Unable to run and unwilling to throw much to other players, the Bucs' offense is Johnson & Johnson and nothing else. It's costing the Bucs a chance to go the playoffs and it may cost Dungy his job. He's in the next-to-last year of his contract.

"It doesn't mean anything if you are bringing guys in without executing and doing what they were supposed to do," Keyshawn Johnson said. "Offensively, defensively, special teams and coaching, we're not doing what we're supposed to do and you're not going to win any football games. All-star casts aren't guaranteed victories."

Brad Johnson completed 18 of 40 passes for 191 yards and was intercepted twice. He took the loss hard.

"This is the worst loss a lot of us have had in a few years," he said. "We were in the ball game in the first half, but midway through the third quarter, it got away from us."

Dungy echoed the embarrassment.

	“	It was disappointing. Only getting three points was disappointing. It's a tough loss, but we are sitting at 7-6. We basically have got to come home and beat New Orleans. We've been in a must-win situation for a long time. ”

"We haven't had a loss like this in a long time where, basically at 10 minutes left in the third quarter, we are out of it," Dungy said. "We weren't able to stop them and get the ball back to our offense in the fourth quarter. It was disappointing. Only getting three points was disappointing. It's a tough loss, but we are sitting at 7-6. We basically have got to come home and beat New Orleans. We've been in a must-win situation for a long time."

Dungy believes that the Saints will let Ricky Williams try to beat the Bucs. The Bears rushed for 162 yards in the second half after getting a 13-3 halftime lead. Rookie Anthony Thomas gained more than half of his 173 yards by running at defensive end Simeon Rice, who was effective getting two sacks on Jim Miller but was buried on running downs.

"We've opened up Pandora's box in the run defense," Dungy said. "New Orleans and Ricky Williams, I'm sure, will look at these tapes, so we've got to look at it, make the corrections, see what the problem was and go back to work on Wednesday."

From the tapes, Dungy will see the Bears sending guards and even right tackle James "Big Cat" Williams across the field to overpower the Bucs' right side of the defense. Expect Kyle Turley, the Saints' right tackle, to try a few of those power plays.

Except for once when David Terrell got behind safety Dexter Jackson for a 62-yard gain in the second quarter, the Bucs' pass defense held up. It allowed a net 172 yards.

A Keyshawn Johnson fumble wasn't the problem. The Bucs have many problems, but they are still in the hunt.
