Allen Park — The Detroit Lions found a cornerstone piece in Kerryon Johnson via last year's draft, but the team's backfield rotation could look far different next season.
Veteran LeGarrette Blount, who led the team with 154 carries in 2018, is a free agent. So is Zach Zenner, who was productive down the stretch after returning from a pair of broken bones in his back. And Theo Riddick, the team's best third-down option the past few seasons because of his pass-catching and pass-blocking ability, is a potential cap casualty with a $4.
