It makes me wonder if Jaylon, who might have been whining about playing time being cut, played intentionally worse this year to get cut to go to a team that would play him more.
Personally, I am not sure that's the cause, but it's possible. I think he just believed in his own "greatness" so much he didn't do what it took mentally off the field (like study tape) to be anything but the fifth best LB on the Cowboys. If he's an upgrade in Green Bay, they really suck at picking linebackers.
Best of luck to him except when he plays against the Cowboys.
