The first rule of Fantasy Football is "ignore Tre".
First of all, Mike Bell has as much if not more of a shot to make an impact than the other rookie running backs. Not sold on him keeping the job? Good, you should never be sold on a rookie keeping the job. It's about risk versus reward. 1500 yards and 15 touchdowns versus wasted pick. He's been named the starter and three weeks in isn't even close to letting it go. Shanahan is as impressed now as he was before. Best case 1500/15 worst case 950/8 Worth it.
