LAKE FOREST, Ill. -- Lovie Smith will return for the Chicago Bears next season.

But he's done calling the defensive plays. His staff will have a new look, too.

The team fired offensive coordinator Ron Turner and five other coaches on that side of the ball Tuesday after going 7-9 with Jay Cutler at quarterback and missing the playoffs for the third straight year following a Super Bowl run.

The Bears have contacted USC offensive coordinator Jeremy Bates about becoming their offensive coordinator, a source close to the situation told ESPN NFL Insider Adam Schefter. Bates worked in Denver with Jay Cutler.

In addition, former Notre Dame coach Charlie Weis is interested in the possibility of coming to Chicago, and he is currently holding off pursuing a similar role with the Kansas City Chiefs because of Tuesday's developments, a source close to the Bears told ESPNChicago.com's Jeff Dickerson.

Former Rams head coach Mike Martz also said he'd be interested in the job, but said he hasn't been contacted by the Bears.

"Absolutely, of course I would [be interested]," Martz said. "But I've never talked to anybody or been contacted by anybody.

"It would be unfair to [Bears coach Lovie Smith] to jump ahead in any process and be involved in it. We'll just wait and see whether things develop."

"This has been a frustrating season to say the least. We've had inconsistent play on both sides of the ball," team president and CEO Ted Phillips said. "Personally, it's been the most frustrating year since I've been here."

He added: "The last three years, it's been clear nobody did a good enough job in the organization. Nobody did."

The Bears had problems on offense and defense and fell far short of expectations after the blockbuster trade with Denver to get Cutler. But instead of bringing in a big-name coach like Bill Cowher, the Bears stuck with Smith, who has two years and $11 million left on his contract.

General manager Jerry Angelo, who was also under scrutiny, said he asked ownership if they wanted to go with a high-profile coach and would have understood if they did. Phillips, meanwhile, said Angelo recommended keeping Smith for a seventh season and that money was "a non-factor."

"If we didn't believe as an organization that Lovie and Jerry could turn this around and get us back to our winning ways, then there would have been other changes made," Phillips said.

But he had also made it clear: The Bears had better win next season.

"We all know what we need to do," he said. "We're not happy. We're not happy with the season we had. We're not happy with the last three years, and the expectation is to turn it around in 2010. At the end of 2010, we'll go through another evaluation process and see where we're at."

At the moment, they're not in a good spot. They've finished 7-9 in two of the past three seasons, and are trying to overhaul their staff at a time when the coach appears to be on shaky ground and potential labor issues loom.

"People will [still] want to come here," Smith said.

Turner's second stint as Chicago's offensive coordinator lasted five years, a run that included two playoff appearances but ended with the Bears ranked 23rd in yards per game and 29th in rushing. A frosty relationship with Cutler probably didn't help, either.

"I did the best job I could with what I had," Turner told The Chicago Tribune.

Also fired were coaches Pep Hamilton (quarterbacks), Rob Boras (tight ends), Harry Hiestand (line), and assistants Luke Butkus and Charles London.

"I'm not going to say everything that went wrong with this football team is because of how we ran our offense," Angelo said. "No. That's not right. It's a combination of a lot of things here."

Smith said he will look outside for a defensive coordinator and that line coach Rod Marinelli is not a candidate for that job. For all the moves, though, Smith said he's looking for coaches with similar philosophies. And that "no matter who comes in here, we're going to have to run the football."

"Changing schemes and all that, I think you have to stay with what you believe in," Smith said. "Obviously, you want a winning football team. ... We've been in a position where we've won with the things that we believe in, so why can't we do that?"

The Bears dropped eight of 10 following a 3-1 start, and as the losses mounted, so did speculation about Smith's job status. Angelo at one point refused to say that Smith would be back while insisting there was no need for a roster overhaul.

After finishing the season with wins over NFC North champion Minnesota and Detroit, Smith has a a 52-44 record since replacing Dick Jauron before the 2004 season.

Chicago went from 11 losses to 11 wins in the first two years under Smith, who was St. Louis' defensive coordinator, before going 13-3 in 2006 and making a run to the Super Bowl. Since then, the Bears are 23-25 and have finished below .500 twice.

The problems this year were well-documented.

Cutler was often scrambling for his life behind a struggling line and threw 26 interceptions, the most by a Bears quarterback since Sid Luckman's club record 31 in 1947 and the most in the NFL since Brett Favre threw 29 for Green Bay in 2005. He was under pressure, but he also made bad decisions while running back Matt Forte faltered after a promising rookie season.

There were a few positives, though.

Cutler's 3,666 yards passing were second-most by a Bears quarterback behind Erik Kramer's 3,838 in 1995, and an inexperienced receiving corps showed some promise. Johnny Knox ranked seventh among rookies with 45 catches for 527 yards and Devin Aromashodu came on strong over the final month and finished with 298 yards.

"He came into a difficult situation with the expectations as high as they were," Turner said Wednesday on the "Waddle & Silvy Show" on ESPN 1000. "As soon as he got here everybody said 'Jay Cutler is here,' and now the expectations went through the roof. I don't know if that was realistic with the issues we had on the offensive line with the young receivers. We all knew it was going to take some time. I'm not sure anybody else did. I think there was a huge weight on his shoulders to come in and really produce at a high level."

While the hammer fell on Turner, the defense wasn't much better even with Smith as the de facto coordinator after stripping the play-calling duties from Bob Babich, who officially still held the title while serving as linebackers coach.

The Bears lost star linebacker Brian Urlacher to a season-ending injury in the opener at Green Bay, a big loss for a team that was hoping to contend in the NFC, and the defense never showed the dominant form that led Chicago to the playoffs in 2005 and 2006. They were 17th in yards allowed, 21st in scoring and 27th in third-down conversions allowed.

"The years that we've been here, how many years have we been bad on third downs?" Smith said. "One. Pretty much this past year. ... Our system, most people want to know what we do on third downs. They buy into what we've done."

Team owner Virginia McCaskey, who watched the news conference from an auditorium balcony, and the McCaskey family issued a statement that expressed support for the changes.

"This season was difficult for everyone," the McCaskeys said. "We are thankful to Bears fans for their passion and are committed to bringing them a winner. The entire Chicago Bears organization understands the importance of being a consistent contender."
