I'm not big on Beanie right now, and Knox is playing the Lions, but I'd still put in Beanie over Knox just because I always go with the RB for my flex position when it's close. This Bears-Lions matchup could be the first big upset of the season if the Bears' O-line doesn't show up and Cutler can't get rid of the ball.
