The Week 12 matchup between the Bears and Vikings revealed a potential changing of the guard in Chicago's backfield. Rookie RB Roschon Johnson had a breakout performance with 75 scrimmage yards on 15 touches, playing on 74.6% of the team's snaps. Meanwhile, Khalil Herbert, the usual starter, saw limited playing time and may still be recovering from an ankle injury. Fantasy managers in deeper leagues should consider adding Johnson off the waiver wire.
