Yes. He has eyes.

He reads WHEN holes or creases are about to open, gives those little head-and-shoulders moves that freeze backers enough for him to cut the other way. and scoots through whatever opening is there, often with enough of a mini-stutter step to freeze a pursuer into a wrong angle.

Or that's the best way for me to describe him. How do you describe a running back's moves?

Last season I wrote that Rivers reminded me of Dick Bass, who did the same things. Williams, not that there is the Cards highlight video to review. reminds me of Bass even more.
