Kevin Jones' ACL tear puts the Detroit backfield right where they were at this point last season: in deep Millen. It's uncertain if Jones suffered a partial or full tear at this point, but any surgery would mean another lost offseason. Jones will have suffered two of the most devastating football injuries in successive seasons during the prime of his career. It's fair to wonder if Jones even will have a prime like many of us envisioned.

The Lions have no depth at running back. T.J. Duckett had a career-high 102 yards on Sunday against Kansas City, but he's about to be a free agent. He makes a decent spare part, but the Lions probably want a runner with more upside to challenge Jones next year or split carries. Tatum Bell has been a bust and will be lucky to be in the NFL next year. Former third-round pick Brian Calhoun can't stay healthy.

Like many Lions decisions on offense, their choices will depend on whether Mike Martz is back next season. It looks 50-50 right now. Kevin Jones dynasty league owners can only hope the odds are that good that their guy will ever develop into a true RB1.
