If there is such a thing as "high-octane defense," then the Bears have it. It doesn't matter what anyone says, Chicago's defensive stars are still studs.
Lance Briggs and Brian Urlacher, arguably one of the best linebacker duos to ever play the game, played solid football all year long at 30-plus years old. Briggs got elected to his seventh consecutive Pro Bowl and Urlacher to his eighth overall. Both players had impressive stats of more than 100 total tackles a piece and combined totals of two forced fumbles and four interceptions.
Charles Tillman also got elected to the Pro Bowl, and it was about time, too. Tillman has played corner back in Chicago's Tampa 2 defense for several years at an above-average level. He also racked up a total of 99 tackles, which is phenomenal for a defensive back.
And don't forget about Julius Peppers. This season wasn't his best, but any offensive coordinator will tell you that Peppers is one of the biggest defensive threats in the entire league. His motor is still running strong.
These stars don't have a long time left in the NFL, but they haven't shown the conventional signs of aging. A good few years of solid production are left in these veterans.
