It's wait and see with Cousins. Remember Matt Cassel, Matt Flynn and *cough* Brock Osweiler? One year(game) wonders are often overpaid.
I love Gang Green but I have a feeling they're not sold on Fitz. They may have to rely on him since it's the aging Forte and a bunch of benchwarmers on their RB roster. But with Marshall and Decker catching everything and anything coming their way, even Geno would be acceptable at QB.
