I'm not worried about Marshall and Decker. Marshall was Geno's best buddy when he first joined the team, and then had a great season last year with Fitz. Saw Marshall giving Geno pep talk before he came on the field Monday night, so Marshall will support whoever is QB. Decker won't see the field this year or next, so who cares what he thinks or says. Never been in an NFL locker room, but from what I hear guys who aren't on the field practicing and playing hold very little sway.
My thought was that Fitz would be back next year, but as a backup. I think that management and coaching staff are going to give Petty and Hack every opportunity to start next year with Geno being cut. That leaves Fitz as the mentor for these two young guys.
