San Diego isn't nearly good enough to overcome its multitude of injuries to beat many teams by more than a field goal, including the Bears.

The Chargers have lost six of their last seven game. They are on a four-game losing streak. The Chargers' two victories have come by a total of eight points. Those wins were against the Lions and Browns, whose combined record is 3-14.

Chicago has been better than perceived thanks to excellent coaching from head coach John Fox and offensive coordinator Adam Gase, both of whom came from the Broncos and are very familiar with San Diego. The Chargers, though, aren't so familiar with the Bears, who they last played in 2011.

Each of the Bears' last four games have been decided by three or fewer points. Jay Cutler has been much better this season. He's been aided greatly by the well-respected Gase. Having Alshon Jeffery back makes a huge difference for Chicago's offense. The Chargers have surrendered 24 or more points in every one of their games.

San Diego has zero rushing touchdowns in its last seven games. Chicago hasn't yielded a rushing touchdown in its last five games. Philip Rivers is having another super season, but the Chargers are not balanced and minus their best wide receiver, Keenan Allen.

Chicago won't have Matt Forte. But Jeremy Langford is an underrated backup and Chicago is far healthier than the Chargers.

San Diego will be without its left tackle and center. The Chargers also could be down a third starting offensive lineman as left guard Orlando Franklin is doubtful. Tight end Ladarius Green isn't likely to play either.

The Chargers are beat up, too, defensively. Linebackers Manti Te'o and Denzel Perryman are out. Three other key defenders - lineman Corey Liuget, cornerback Jason Verrett and safety Eric Weddle - are questionable.

Unlike the Bears, the Chargers have not had their bye yet. That comes next week. They are battered and worn down. It's too much to ask them to cover a point spread of more than a field goal.
