The suspension to has said that it'll be hard to replace Gates with Green. Rather, Reich noted that isn't expected to be the workhorse, and it's pretty clear that Woodhead should have a pretty significant role in the Chargers offense, a unit that ranked 11th in per-play efficiency, according to our metrics, last year.

Detroit was, by far, the best run defense in the league according to our metrics last year, but they no longer have Ndamukong Suh or Nick Fairley up front. It'll still be a formidable defense, but Woodhead should have plenty of functions rather than simply running between the tackles in Week 1.
