The only guy on the radar who really intrigues me is Cam Newton. If he gets released and is willing to come here on a cheap one year prove it deal, he's worth a flyer (assuming the medicals aren't too gnarly). If it works out, great. If not, wouldn't cost much and they'll continue developing Stidham either way.
I was living in the Carolinas when Cam entered the league, so I watched a lot of those Panthers games, and it was impossible not to be impressed with him. Cam is a unique QB that can do some crazy stuff on the football field, when he's healthy.
Newton has burned the Pats both times they've played him. Belichick praised the shit out of him heading into the 2017 game, even beyond the typical ball-washing he does of every player on every opponent in his press conferences. Made it a point to call him a good decision maker, a quality of Newton's that is underrated. So there could be some interest there. Him in a McDaniels offense could be pretty fun.
