Redskins beat writer Mike Jones on the team's running backs, Alfred Morris and Matt Jones:
If things hold true throughout training camp, then I’d expect to see Morris continue as the workhorse back. Coaches will most likely use Jones to give Morris a breather here in there, or both on short-yardage situations, and on third downs.
In his first three seasons, Morris has finished #5, #14 and #13 in standard formats. He's more of a RB2 in PPR leagues (#7, #19, #17) since he has only averaged 0.8 receptions per game in his career. Bill Callahan's arrival (as offensive line coach) should boost the effectiveness of the team's running game, which in turn will help Morris's fantasy production. He's a solid value and a safe pick in the 3rd/4th round of early PPR drafts.
