Best of 2012: Kansas City ChiefsTake a look at the best photos from the Kansas City Chiefs' 2012 season.
Boss' future in the NFL is sadly uncertain because of his history of concussions. Breaston was brought to Kansas City by Todd Haley, but his production fell off a cliff in 2011. Breaston could barely get on the field last year after totaling 785 yards in 2011.
There should be a role for Breaston, 30, as a slot man somewhere. But he was due almost $4 million in 2013.
Boss was a terrific starter for the Giants, but he struggled to make an impact in Oakland and Kansas City the last two years. Boss only played two games for the Chiefs because of a severe concussion. He was due to make $2.4 million.
Moves like these could help the Chiefs sign big-ticket items like wide receiver Dwayne Bowe and tackle Branden Albert. NFL.com's Ian Rapoport reported that the Chiefs are in long-term talks with both players. One of them could wind up getting the franchise tag.Follow Gregg Rosenthal on Twitter @greggrosenthal.
