It wouldn't be a bad thing for the Lions' offense if Bell sits until he's fully healthy -- he underwent surgeries for his knee and Achilles this offseason.
Bell has 20 carries for 22 yards and a touchdown on the season. Bell's 1.1 yards per carry is the second lowest in the league among players with at least 10 carries. The big back has forced just one missed tackle, via Pro Football Focus.
Ameer Abdullah should earn the majority of snaps with Bell out. The rookie brings the potential to break a big gain that Bell doesn't possess. Preseason hype bunny Zach Zenner would be the candidate to get short-yardage and between-the-tackles runs. Pass-catching back Theo Riddick should see more time as well.
While Bell's story from Wayne State University to the NFL is a great one, at this point the Lions backfield has better options, especially if he isn't healthy.
