LAKE FOREST, Ill. — Bears QB Jay Cutler said he and his teammates on offense are not overwhelmed by offensive coordinator Mike Martz's system, although Martz has pointed the finger at himself multiple times this season for trying to do too much.

"Mike's going to take the blame," Cutler said at his press conference Wednesday. "That's just kind of how Mike is. As players we have to take more responsibility for this. We've been in the system long enough. Everyone should know what to do. We should be able to execute on the field."

Cutler was asked what he needs to do better to help solve some of the problems.

"Everything," he said. "We need to take a hard look at all of ourselves on offense, myself included. We need to execute better."

The Bears are alone in first place in the NFC North, but they rank 29th in offense and Cutler has been sacked a league-high 23 times, even though he missed 1½ games with a concussion.

"They're excellent coaches," Cutler said of Chicago's offensive staff. "They're doing everything possible to put us in a position to be successful, telling us every little detail we need to know. We just need to go out and do it."
