The Eagles cut OT Dennis Kelly, to me he's a swing tackle candidate. More details of him https://www.philadelphiaeagles.com/news/eagles-sign-veteran-dennis-kelly when they first signed him.
And he only played 9 games in high school...

Jerry may love Dak.but think he also sees that he might not be good enough so might as well bring in a guy to develop behind him. I wonder if it makes Cooper Rush available?
