Willis McGahee has been criticized for not showing commitment to the Ravens and may have to learn by sharing time with other running backs, according to Baltimore Sun. McGahee is expected to make his first appearance for the team this season on Monday night against Houston after missing the team's opener with a knee injury. "I want a full workload, but that's something the coaches have to figure out," McGahee said. Baltimore appears primed to use a running back-by-committee system for the time-being. "As of today, he's got a role in this game," Offensive Coordinator Cam Cameron said Thursday. "We ultimately aren't going to know until he's practiced through the end of the week."
