Denver Broncos head coach Vance Joseph is planning on using a running-back-by-committee system in the upcoming season. ‘You need two or three guys that can carry the load,’ Joseph said. ‘It is no longer a one-guy position. I’m excited to have Jamaal (Charles), C.J. (Anderson), (Devontae Booker), even De’Angelo (Henderson) in the mix there. It’s a good group. It’s going to be competitive, and that’s the way it should be.’
