When the Chicago Bears went to the Super Bowl in 2006, they did so on the strength of their defense and special teams. Their defensive coordinator that season was Ron Rivera, who is now the DC for the San Diego Chargers.

The reason Rivera is out in San Diego instead of still coaching the D in Chicago is because head coach Lovie Smith promoted close friend Bob Babich to defensive coordinator, instead of keeping the guy that had just got him to the Super Bowl.

Now Smith is in a hell of his own making as the Bears currently sit at 5-5 on the year and are owners of the 19th ranked defense in the NFL. While it’s true injuries have ransacked Chicago’s defense, there’s no excuse for the poor tackling that the Bears demonstrated in Green Bay on Sunday, or the utter collapse earlier this year against the Falcons when Matt Ryan was allowed to complete a long out pattern to Michael Jenkins to set up a Jason Elam-game winning field goal.

One Chicago Sun-Times contributor writes that Smith should fire Babich and end the charade. That’s hard to argue when you witness a Bears’ defense that continuously is overmatched, under prepared and out schemed on a weekly basis. I mean, how many times will you allow teams to beat your Cover 2 defense before you make adjustments?

Somebody has to take blame for the collapse of the Chicago defense and I think it’s fair to say that Smith and Babich deserve a 50/50 split. If Smith would have allowed Rivera to make the adjustments he wanted to make following the Super Bowl in 2006, than maybe the Bears would be running away with the hapless NFC North right now. Instead, Smith is stuck with his buddy and a defense that is currently surrendering close to 25 points a game.
