I really hope not tbh. If we do, we're going to have to basically start over from scratch on defense and start drafting 4-3 players. It's not just a scheme change, it's all about personel. We don't have the players for it outside of a couple guys. Ware would basically be useless except for obvious passing downs, as would Spencer.
I say we stick to the 3-4 and continue to build it up. But, knowing Jerry, he'll probably make the worst decision possible and we will continue to suck.
