Three position battles — not counting the quarterback — we’ll be watching when the Bears scrimmage at Solider Field on Saturday:
Running back: Ryan Nall vs. Artavis Pierce
David Montgomery’s groin injury is expected to cost him weeks, not months. That might eliminate the need for a signing — and the attraction level for a potential free agent.
If the Bears carry their four healthy running backs into Week 1, then, either Pierce or Nall could be in line for carries. Tarik Cohen has carried the ball more than nine times just once under coach Matt Nagy, and Cordarrelle Patterson, a receiver by trade, has never posted more than 11 rushes in game.
