16 Team PPR
Currently, own Dwayne Allen and Charles Clay. Should I drop Clay and pick up Virgil Green?
You could, but I don't think it's necessary. Since you've got Dwayne Allen, I'd probably rather have Clay since he's the better combination of safety and upside. Green probably has more upside, but he seems less of a plug-and-play guy to me. Clay has shown when he's healthy that he can be a borderline TE1.
