The Chicago Bears allowed a sack on 9.4% of their pass plays, good for second-worst in the NFL and a total of 49 sacks in the 2011 season. And unsurprisingly, the Bears sack-recipient, QB Jay Cutler, is a little worried about the offensive line's development:

"You always want to be pro-Bears and compliment your teammates and stuff but ... over a three-year career here (the offensive line is) definitely at the forefront of my mind ever year. Until we get those front five hammered down we're still kind of up in the air offensively even though we've got some really, really talented guys on the outside."

Chicago hopes to improve on their 8-8 record in the 2012 season, having added WR Brandon Marshall and free agents QB Jason Campbell and RB Michael Bush.
