In fairness to Ballard, he has always spoke highly about Williams, even when he was always a healthy scratch this past year and a half. He never dropped him to the practice squad as he was afraid he was going to be picked up. We saw why today.
Also, all of people have been calling to bring in a more physical, one-cut running back to backup Mack. It could be we always had that with Williams! Hopefully Mack can get back for Houston, I'd like to see a Mack/Williams 1-2 punch the next day.
