The wildcard in that mix is Marsh. I am not a big fan of his game, but he is one of those guys that some coaches like and will stick around and push a young talent off the roster. I think Roche needs to make the 53 and Jones I like, but he has a shot at sticking on the practice squad if they only keep 4.
But Marsh is like the Carey Davis of OLB's and could also end up making it at that position.
