Redskins offensive coordinator Mat Cavanaugh indicated that they will play (the running game) by ear.
“(Rob Kelley) obviously has earned the starting job, and I think really it’s a game-to-game evaluation, an in-game evaluation of how well he’s doing and how winded he is – ‘Does he need a blow?’ said Cavanaugh. “We just feel like we’ve got depth at that position now with a lot of similar-type players: stocky, quick-footed, strong, smart guys that can sub in for each other. I wouldn’t put a pitch count on any of them, but obviously if a guy’s got a hot hand and he’s feeling good and he’s not gassed, we’ll keep him on the field. Ideally, maybe have some third-down reps too.”
That last part means that they could play Kelley or Samaje Perine on third downs. They could also expand Thompson out of his usual third-down role.
“Historically here, Chris has been our third-down back, but there’s no reason why can’t play him on first and second down,” said Cavanaugh. “But just rotating the backs, keeping them fresh, we’ve got confidence in all of them.”
Kelley won the RB1 job in Week 8, and from that point on, he was the #13 RB in standard (#15 in PPR) down the stretch. He averaged 4.19 YPC, which was the 14th highest per carry average of the 27 running backs who saw at least 150 carries last year. Rookie Samaje Perine will make a hard push for the job, but it's clear that Kelley is taking his job seriously by getting leaner in the offseason. He is currently very cheap (10th/11th round) in early drafts.
