Bell, 29, struggled with injuries throughout the 2015 season and was passed on the depth chart by rookie Ameer Abdullah and Theo Riddick. He gained a career-low 311 yards on 90 carries with four touchdowns.
That leaves the Lions with Ameer Abdullah, Theo Riddick and Zach Zenner at the position. Riddick should continue to produce in PPR formats while Abdullah and Zenner will compete for carries. The Lions may decide to address the position in the draft, but they have more pressing needs with Calvin Johnson's pending retirement.
