This has been the NFL season of the free agent running back. When I filed my quarter-season awards column after Week 4, the top two players competing for Offensive Player of the Year honors were the Ravens' Derrick Henry and the Eagles' Saquon Barkley, both of whom were signed away from teams that didn't really want to keep them in unrestricted free agency. My midseason awards are coming up in a couple of weeks, and I'd be surprised if both weren't in the top three again.
Henry and Barkley are having an impact on and off the field.
