I'm not particularly a fan of Mims either, but he did look good against Tennessee and he's apparently done some things in the passing game in camp that they have not shown in the preseason games. Lots of featuring Kamara split out and other routes for Kamara that Mims apparently is good at. But, I can't imagine that they would use Mims as an every down back if AK gets hurt. I think they would start Williams and use Mims as the 3rd down back.
