Eagles RBs coach Jamel Singleton hinted that his team plans on deploying a committee backfield in 2021. "There are very specific skill sets you need in your room," Singleton said. "You need a first- and second-down runner with that really elite ability. You need a guy that can pass protect on third down and be short yardage. You need a back that can run routes and you can put him out in empty. It’s really a combination of that. I think the days of, ‘he’s an every-down back,’ that’s a little skewed these days because of the speed, because of the contact.” There are very few every-down backs in today's NFL, so this certainly isn't a death knell to Miles Sanders. But we're curious to see exactly how much work he'll cede after the Eagles added rookie RB Kenneth Gainwell and RB Kerryon Johnson to a group that already included RBs Boston Scott and Jordan Howard.
