Bears try to exploit cornerback weakness

Running backs

Grade: 7

Matt Forte set up the Bears' lone touchdown with a 39-yard run. Other than that, he averaged 2.7 yards per carry. He made some nice contributions in pass protection.

Tight ends

Grade: 3

Kellen Davis struggled with blocking assignments and dropped a pass. Matt Spaeth dropped another pass. Spaeth and Kyle Adams made some contributions as blockers.

Offensive line

Grade: 5

Let's start with this: The pass protection was pretty good, considering it was up against what might be the most talented defensive line in football. J'Marcus Webb had another nice game.

There were five sacks, but only one of them was the result of offensive linemen getting flat-out beat.

On the play in which Cutler was injured, three Bears tried to block Ndamukong Suh. He escaped an initial double team attempt of Lance Louis and Gabe Carimi by leveraging Louis to Louis' right toward Carimi and then shooting the gap. Roberto Garza then tried to help but wasn't quick enough.

It was a four-man rush and a seven-man protection, and the sack never should have happened.

The run blocking was inconsistent. On Forte's 39-yard run, Chilo Rachal took care of Nick Fairley and Louis pulled to get to safety Louis Delmas. But Rachal missed Fairley when the Bears were backed up on their own goal line, and it nearly led to a safety.

The worst part: Bears offensive linemen were flagged six times. Carimi and Garza were flagged twice. Only Webb did not commit an infraction.

Defensive line

Grade: 8.5

The Bears kept the heat on Matthew Stafford pretty well. Part of this was because they sent extra rushers 14 times, which is a high number of blitzes for them.

But there were pass rush contributions from virtually every defensive lineman.

Julius Peppers had a sack, two hits and five pressures. He literally threw blockers to the ground on two occasions. And the Lions were aware of him, sometimes playing Riley Reiff as a sixth offensive lineman/tight end on Peppers' side.

This probably was Shea McClellin's best game. Peppers' sack came courtesy of McClellin, who forced Stafford to step up into Peppers.
