No idea if this is true, but Sweat is exactly the type of player this defense needs. He'd give the Packers a legit pass rush while Micah Parsons is out early in the season, and pairing him with Parsons could make the pass rush dominant enough to compensate for the slop at corner.
Hearing the Packers and Cardinals are working on a trade involving Josh Sweat, per source. It is coming down to how much cap the Packers are willing to take, and how high of a pick.
