The Tennessee Titans are reportedly trying to trade Chris Johnson. While this isn't news, it is surprising that there are (conflicting) reports that say CJ might take a pay cut to be traded. If he does actually take a pay cut, then some of the playoff teams in the league may take a flier on him as a backup/counter running back. These three teams are the teams I believe would be the best fits for CJ.
San Francisco 49ers:
The 49ers have tons of picks, and after trading for Blaine Gabbert and Jonathan Martin, literally anything seems possible. CJ is a durable back who would have space thanks to the 49ers OL. Also, he would be a great change of pace back behind Frank Gore if Marcus Lattimore isn't ready/doesn't develop.
Seattle Seahawks:
While the Seahawks don't have the picks, CJ on a reduced salary makes a lot of sense. With Russell Wilson and Percy Harvin stretching the field, CJ could have a lot of room to move. In Seattle, he could be the flash that goes with the Marshawn Lynch hammer.
Kansas City Chiefs:
The Chiefs had a very good offensive line, and though they lost some good pieces, Andy Reid should be able to address that in the draft. On a team without many needs, the Chiefs could make a competitive bid for Chris Johnson and again, as a number two back behind Jamaal Charles he could be a quality player.
