But you know what? So what!
His numbers weren't very good last preseason either and he kicked some butt in the regular season.
Williams is lighter and faster than he was last season, so we can expect more long runs like he had last season when he led the NFL with 57 runs of 10 yards or more.
Now is the time when Williams will get a full dose of work, and that's why the preseason is so bogus when it comes to evaluating his progress.
The guy is a stud. Period. End of story.
He might not rush for 1,853 yards again this season, but he will be very productive again. And he's obviously the guy who is going to make the Dolphins offense go.
