Wake returns basically the entire O, but losses the entire D, which had like 5 NFLers on it and their K who was the tits. I would be scared of this game because I don't really know what to expect from either, but I would bet on Wake cause it is at the BB&T.
Wake - by virtue of sitting everyone until their RSJr year - has some seriously mature and developed talent to replace their two stars on defense. It wont be as good (their defense) but it's not going to be bad.
