Urlacher replacement idea

At some point in the near future, the Chicago Bears will have to find a replacement for Brian Urlacher. Urlacher may have some seasons left before he retires, but there will be a day when someone else will be their starting middle linebacker. A lot of attention has been paid to whether that will occur in 2013, as Urlacher's contract is up this offseason, and that's an intriguing storyline we'll continue to follow, but what about the next step in the process: finding someone to fill his role?
