This is the final installment of our Roster Turnover series, if you missed any of the 13 parts you can click here to access the full storystream.

Charles Tillman - Signed through 2013 - Tillman came through with another Pro Bowl performance in 2012, and there was a time there when he was actually being mentioned as a possible NFL defensive MVP. At this point in his career he's really accumulating Hall Of Fame type numbers. His 9 defensive touchdowns are the most in the long and storied history of the Chicago Bears. His 33 interceptions are within shouting distance of Gary Fencik's franchise best 38, and he passed Hall Of Famer Richard Dent to become the Bears leader in forced fumbles with 37 (link).

Pro Football Focus had Tillman's '12 season graded as the 4th best among corners last year. His +22.8 was a career best for Peanut, and it was the highest of any Bear that doesn't make a living kicking. There's really nothing negative to say about Tillman.

Even though he just turned 32 years old, he does seem to be improving with age, and a contract extension may make a lot of sense. His base salary for 2013 is nearly $8 million, so the Bears could offer a 2 year extension, add in some guaranteed money, and bring down his cap hit for this year.

Tim Jennings - Signed through 2013 - Jennings is an awesome example of a player that identified a weakness in his game, worked hard on it during the off season, and was able to see dividends on all his hard work. Jennings, who will turn 30 on Christmas Eve, is another candidate for a contract extension this year. He's due $4.25 million for a base salary this season, and he's been fairly durable for his career. Since 2008 he's only missed three games.

He was the #9 corner according to the PFF graders, with a +12.4. Among corners that played at least half of their teams snaps, Jennings had the 3rd lowest QB rating against (53.3) when QBs threw in his direction.

D.J. Moore - Free agent - Moore kind of fell out of favor with Lovie Smith and Rod Marinelli, and if he were under contract I'd say a fresh start was in the cards, but with his contract up he may be allowed to leave. He did grade out with a +3.1 while playing nickle, so I suppose the new regime could watch the film and decide he's worth another deal. My gut says we've seen the last of D.J. Moore in a Bears uniform.
