If he realizes his potential you're wrong the man is too good yes his speed his first step,,,,, The man has natural athletic ability and instincts so maybe he gets a fresh start with this coaching staff and I don't think he's the odd man out some of them guys are not pass rushers they're more in the run fits I mean after Sam Williams that whole list down there are guys that are better at stopping to run they're not exactly natural pass rushers.
It's why you were right the first time sam Williams gives the Cowboys along with the other three guys opportunities that be interchangeable and have them all on the field at the same time like you said Sam could take over Parson's spot for a couple plays parsons can play off the ball linebacker if needed occasionally and they can do all kinds of things..
