This. If you watched the game yesterday, you saw exactly what I, and some others here, were saying. Riddick has a role, he's exceptional at it, but he will not excel if that role is expanded. Washington gives them something different. He looks fast, strong, and decisive. He's not going to be a 20+ touch workhorse, that isn't the way the Lion's use their RB's. His upside will be 15 or so carries, a few catches, and the GL work. It's good RB2/Flex material. It will be dictated by matchup.
This week showed that Washington, contrary to some posters opinions, had in fact secured the "Big Back" role here in Detroit, was not threatened by Zenner, and looks capable. If you scooped him, congratulations. If you started him, that was too soon, but not be discouraged. In games where the Lion's aren't down 20+ before the crowd is seated, he should have a valuable and useful role.
