Even now, almost a week later, it still eats at him.
While everyone else focuses on his interception of Browns backup quarterback Johnny Manziel, Williams was fixated on the play he didn't make: a 20-yard completion by Cleveland's Travis Benjamin.

The second-year cornerback -- who sprang into action after veteran Antonio Cromartie was carted off the field with a knee injury -- is now a highly sought-after interview subject thanks to his burgeoning role on defense.
