Fantasy Advice: If Kevin Smith hadn't suffered a high-ankle sprain, the team could have waited on Best a little bit longer. But with Smith out for the forseeable future, the Lions will have to make a move for running back depth behind Maurice Morris and Keiland Williams. Best's dynasty value is also on troubled ground due to so many concussions in such a short amount of time. The Lions will have to rely on Matthew Stafford and their passing game for the rest of the year.
