No surprises here really. The Chargers just signed Michel to at least help compliment Ekeler. While the Dolphins cut Michel, it seems like the Bolts aren't totally sold on going with Kelley as the backup, even though he had a nice camp, according to reports. Spiller was banged up a bit this offseason so he'll likely need more time before he's fantasy relevant and gets to move up the depth chart.
LAR RB Sony Michel - Week 17 Fantasy Football Outlook
Week 17 at Baltimore Ravens
Until Cam Akers is given the keys to the Rams running game, Michel is the guy. The only issue is that the Ravens are one of the best run defenses in the NFL (5th in aFPA). If Michel can get incorporated in the passing game a la Joe Mixon, his fantasy floor is much higher. Michel may end up being a clock killer that gets 20 rushes but low yardage in a game that the Rams should win.
