I suppose they can franchise tag him but I think it would cost about $15mil considering the top WR are getting paid around 20mil. Not cheap and considering they have so many weapons, some of these guys are luxuries they can't afford.
If they keep Evans, would they keep both AB if he affordable and Godwin? They can be replaced with Amendola and Edelman at 1/3 the cost. They still have Miller and other up and comers.
Also have to consider that I think Gronk will be back. OJ Howard will be back. Brate could be back if he agrees to less.
For RB, Vaughn looks really good. I think White and Burkhead are FA and could be cheap.
So next year looks like a case of too many weapons with too many mouths to feed again. A nice problem to have. So to me Godwin looks like a luxury even if they also lose AB.
