No, I don't see how that helps you. McFadden should be starting, not Greene. But you are downgrading QB and RB for a WR who shouldn't start and a decent TE you don't really need. I would do something to not have 2 Raven WRs on your team. Unfortunately, I'm not sure Mason is worth much. But I would see if you can get comparable value at WR by trading either Boldin or mason.
It's easy to look at what he did against the Lions and salivate.
