We're Black and Blue All Over:

As NFL free agency approaches, we're getting an idea of the players teams do and do not want to retain. One that falls in the latter category is Chicago Bears nickelback D.J. Moore, who intercepted 10 passes in three seasons but has been informed the Bears will go in a different direction in 2013.

Moore lost his job midway through last season to veteran Kelvin Hayden, and the Bears' starting cornerback jobs -- even under a new coaching staff -- are locked down by 2012 Pro Bowl players Charles Tillman and Tim Jennings.

Relatively speaking, the Bears are in a position of strength and, naturally, you can't re-sign everyone.
