When Edwards is number 1 on your list.....you know your in trouble!
There are some "solid" WR's available, but I don't think you see any true game changers. I think at this point in his career, Santana Moss is way too high on that list; hell I'd take a 38 yr old TO over S Moss from a production standpoint.
I think the one guy I would aggressively seek if I needed a WR in a bad way would be Mike Sims-Walker. If he can stay healthy, I think he could possibly be that difference maker. I think the character concerns are over blown. James Jones could also be on his way out of GB and has a ton of upside. Will Floyd stay in SD? If they let him go they are fools! If they do, great opportunity for someone.
