Honestly the whole starting D has a chance to get drafted.
I think locks are clayborn, Angerer and Spievey (already drafted), Edds, Hunter, Klug, and Sash. Ballard has the size with a good year should also be drafted. I expect that Binns will to continue to improve and become a great pass rusher / defender with those long arms. And I think Prater and Greenway also have late round potential with solid seasons next year.
