I think Huntley sitting was more to do with getting a better look at JJ and Brown to settle who would be #3.
Yeah, no big deal on the defense, aside from the lack of containment on either end. The secondary is going to look very different come opening day.
Mitchell I know was nursing a shoulder, plus they likely didn't want to expose him too much more to the league to dry and pass him through waivers, stash him on the practice squad.
I would be shocked if they kept him on the active roster over Gordon or that they will keep 5 runningbacks. He showed decent skills in the 2 fake games against second and third stringers, plus what he has done in practice, but he was not asked to pick up a blitz either...
I still have not found much info on Josh Ross, lis franc last year, how he has recovered. If he is healthy, he was clearly much better than anyone at inside backer not named Agent 0 or his side kick Queen.
