This sounds about right to me.
Ever since his move to Washington, he's become just an extremely solid running back. It seems he left those flashes of incredible brilliance behind in Denver, but in turn transformed into more of a workhorse back (which is what Gibbs traded for him to be) who is very good at all things a running back must do. Probably the most complete back in the NFL. Because he isn't the very best at any of what he does, he gets overlooked by fans.
Gotta love his multiple personas, though! Love how he doesn't take himself too seriously.
