Well it's Aaron Donald he's a freak and I don't think he's real old yet, so I'd think he's probably either A. Dealing with injuries this year. or B. Got no help.
I don't know about that he had a bunch of 4th down conversions in that end of the season game against the Raiders last year to get the Chargers into the Playoffs. Staley was awful, and either embodied or was possessed by the Chargers choking fetish.
