"Our coaches actually do a good job of switching it up," cornerback Corey Graham said. "We play man (coverage) more than you probably think. It's just that when we are in man, we've just got to make some plays. Coaches can only do so much. They can make the calls, but eventually you've got to go out there and make some plays and get it done."

Middle linebacker Brian Urlacher had five interceptions and five sacks last season, but he hasn't made nearly as many big plays this year as he has in the past. He also said it isn't the scheme.

"I won defensive player of the year (in 2005) in this scheme, so I must've been doing something right," he told Green Bay-area media. "There are chances for me to make plays. It has nothing to do with the scheme or the calls, it's just a matter of me getting in position to make plays."

PLAYER NOTES

--QB Kyle Orton (sprained right ankle) practiced more Thursday than he did on Wednesday and appears to be the likely starter Sunday, although his availability will be a game-time decision.

--WR Brandon Lloyd (sprained knee) has had a full week of unlimited practice and should be back Sunday, although it remains to be seen if he will be given his starting job back after missing five games (six weeks, including the bye) with a sprained ankle.

--CB Nate Vasher could find himself on the bench Sunday against the Packers if Bears coaches opt for a more physical lineup. That shuffled lineup could see nickel back Corey Graham assume Vasher's role in the starting lineup, with S Danieal Manning regaining the nickel job he lost to Graham.

--CB Charles Tillman (shoulder) was limited again in Thursday's practice but is expected to play on Sunday.

--TE Greg Olsen is ninth in the NFL among tight ends with 29 catches.

--LB Lance Briggs is one of just six NFL players with a forced fumble, recovered fumble, sack and interception this season.

--PK Robbie Gould is fourth all-time in FG accuracy (84.6 percent) among players with 100 attempts, even after having a 48-yard attempt blocked last week.

GAME PLAN: The Bears can talk all they want about stopping the run first and making the Packers one-dimensional, but that formula has been getting them destroyed all season. The Bears are No. 4 in rushing yards allowed, but they rank 17th in total yards allowed because they are 30th in passing yards allowed, and each of the last four quarterbacks to face them has thrown for at least 289 yards. The Bears won't ignore the run, even though the Packers are 23rd in rushing yards and 25th in average gain per rush, but they must be more concerned with QB Aaron Rodgers and a passing game that is No. 11 in yards.

On offense the Bears say they won't change what they do regardless of whether it's Kyle Orton or Rex Grossman at quarterback. But they're clearly more comfortable letting Orton put it up than Grossman, especially against the Packers' opportunistic secondary. They will rely almost exclusively on rookie Matt Forte to establish the ground game, which for them, is always important, but even more so if Grossman starts.

MATCHUPS TO WATCH: Packers WRs Greg Jennings and Donald Driver vs. Bears CBs Charles Tillman and Nate Vasher - Jennings and Driver have a combined 84 catches for 1,313 yards and 7 touchdowns. They attack the maligned Tillman and Vasher, who have been hurt much of the year and criticized for failing to press opposing receivers at the line of scrimmage.

Bears QB Kyle Orton or Rex Grossman vs. Packers secondary: Packer defensive backs have already returned six interceptions for touchdowns this season, including three by FS Nick Collins and two by CB Charles Woodson.
