The Skins have not had a stud RB since Clinton Portis, who changed his body and running style to survive the rigors of carrying the load for Joe Gibbs, and was never really his Denver self again.
Since then, they've tried rolling out the corpses of Fast Willie Parker, Shaun Alexander, Ryan Grant and Larry Johnson, low or no pedigree guys like Alfred Morris, Roy Helu, Evan Royster, Chris Thompson, Matt Jones, Darrel Young, Silas Redd, Lache Seastrunk, Keiland Williams, Ryan Torain, Tim Hightower, Keith Marshall, Mack Brown, Kapri Bibbs, Byron Marshall, Samaje Perine, etc. Sometimes these guys have flamed out, sometimes they've done more than they should due to scheme, and sometimes they were just below replacement-level bodies used by necessity.
He is going to be a revelation for Skins fans. I have no idea what that will mean for fantasy purposes, but this team hasn't had an actual good RB in a long, long time.
