The difference of three years in Chicago

Call me slow, but in putting together last week's post on the future of Chicago tight end Desmond Clark, everything seemed clear: The Bears have turned over nearly 75 percent of their starting lineup since losing Super Bowl XLI four years ago.

Take a look at the chart below. By my count, only six of the 22 starters from that season will return in the same position. The group has been broken up by trade, releases, retirements and the decision not to re-sign veteran free agents.

All teams go through a level of turnover, but the Bears have moved at an accelerated rate over the past two years. They've missed the playoffs for three consecutive years, and one thing is for sure: Whenever they return, it will be with a decidedly fresh-faced team.
