Bears v. Chargers

I know all the problems the Bears are suppose to have but really are the Bears that Bad?  Are the Chargers that good?  I know the AFC is ahead in most ways of the NFC but it is clear that the Bears are being underestimated and the Bears are aware of this.  I think defense is always ahead of offense at this time of the season.   I think the Bears will win a very low scoring game: Bears 13--Chargers 10.

update: after 3 quarters.  Bears defense is great but to many mistakes!  4 turnovers and they are behind 7-3.  I don't see the offense that will take them back to the top but they are only one score from victory but it might be that the defense will have to score for them to win.  The only way the Chargers could score on this great defense was with a trick play.  Ugh! Thomas Jones should still be a Bear!

2nd update--The chargers just scored 14-3.  The Bears defense is tired and the offense has been no help.   

3rd update--now they cannot even pick up one yard on 4th down.
