According to Pro Football Talk a trade market is emerging for running back Chris Johnson. The market for Johnson is from from multiple teams.
For now, nothing is imminent. A trade would require both the Titans to be happy with the compensation and Johnson to be happy with the destination. Johnson also would have to be happy with his contract, but remember CJ2K is from Florida.
A team that could use a good back is the Dolphins. If CJ was to land in Miami it would take quite a bit of stress off of Tannehill. I am sure Johnson would be happy to return to the sunshine state.
