Trouble with putting in a claim is that he would have to be signed to the 53 man roster and he's not ready for that. He would need to learn the playbook and get snaps and that wouldn't happen in season (the practice snaps that is).
Best course is to see if he clears and sign to PS. He's still somewhat raw IMO and running the scout team would be a good start for him. I do think he's got a shot to be a plus backup.
Sneaky Joe had a Tweet that was this same tone not long before this thread was made. Amazing how often that happens. Now, I'm not saying Pepe here saw it and was "inspired" but oh hey look cookies. Brb.
