Bears stats show they miss Mike Brown

In the six games that Mike Brown played last season before he suffered a season-ending foot injury, the Bears allowed just 74.5 rushing yards per game.

But in the next 10 games without Brown, the Bears allowed 114.3 rushing yards per game, and while his absence wasn't the only reason for the decline, it played a part.

"He's always in the right spots," middle linebacker Brian Urlacher said. "You know if he's back there or even around anywhere in the box, he's going to make the tackle. He's going to be in the right spots, so, if we do screw up and get out of our gaps, he'll make up for it."

With Brown out for the season due to injury, those statistics again become a focal point for the defense.

Injury update: Middle linebacker Brian Urlacher (stiff back) and wide receiver Muhsin Muhammad (ankle) were held out of practice Friday, but both are probable for Sunday's game.

Punter Brad Maynard (groin) was limited in practice and is listed as questionable. If Maynard's condition worsens, the Bears could sign a replacement today. The emergency punter is kicker Robbie Gould, who punted once in 2005 for 28 yards.

Tight end Greg Olsen (knee, questionable) was limited again in Friday's practice, but, "He should be available for us," coach Lovie Smith said.

Part of the plan: Since the offense had just 52 plays last week - compared to 71 for the Chargers - coordinator Ron Turner didn't have an opportunity to fully develop his game plan, which included more participation from Devin Hester and Garrett Wolfe.

Hester played one snap - one more than Wolfe - as the Bears managed just 11 first downs, to San Diego's 19.

"We never got into any kind of a rhythm," Turner said. "When you get first downs, there are some things you set up. We were never able to do that. We will get both of those guys involved this week. We will definitely get Devin involved early, and hopefully Garrett as well."

Taking a licking: Surviving the violent first-quarter sack by unblocked Shaun Phillips last week was almost like a badge of courage for quarterback Rex Grossman, but he doesn't want to have to withstand any more.

"It's almost like a scar; it's like, check out this hit I took," Grossman said. "It's not something you're proud of, but at the same time it was the hardest hit I ever took. We'll correct it. We're going to have a lot more fun on Sunday."

Down to business: Despite the opening loss, Brian Urlacher still believes the Bears could run the table if they play to their capabilities, regardless of the opponent.

The Bears and Chiefs had similar offensive struggles in Week One, but Urlacher isn't concerned about the opponent nearly as much as he is with getting things right on the Bears' end.

"We're both 0-1, but I don't look into it very much," he said of the similarities with K.C. "I worry about us, what we have to do to get better and how we can go out there and try and win games. If we take care of business, we should win every game."

Not for everyone: Rex Grossman said he's seen HBO's "Hard Knocks," the behind-the-scenes look at the Chiefs' training camp this season, but he can't envision the Bears ever starring in a similar production.

"I could never see coach Smith having us do that," Grossman said. "I just don't think he has that kind of personality that he wants to show everything we're doing. That's only my guess. I haven't heard his opinion on it."

Grossman's opinion is that he wouldn't be in favor of doing the show either.

"I think being able to sugar-coat some things is nice," he said, "not having everything shown behind the scenes."
