The Detroit Lions have a trio of intriguing running backs in Reggie Bush, Joique Bell and Theo Riddick, but the future of Bush with the team is uncertain.

That's because he has been prone to injury the past couple of seasons, turns 30 in a few weeks and has had diminishing returns in production (2014 3.9 YPC was his lowest mark since 2008). Plus, if the Lions cut Bush, they can shave $4 million off of their salary cap.

If free-agent-to-be Justin Forsett is available at an affordable price, he could be a good match for the Lions to replace Bush.
