I think if the draft were held now, Reggie Nelson would definitely be the #1 safety taken, probably a sure bet as a top 15 pick. Landry might fall to the latter part of Round 1. After them, it seems Rouse & Zbikowski & Griffin are the next best ones, and maybe only 1 or 2 go in Round 1.
Basically, I'd draft anybody from Michigan, since I don't think you can go wrong with any of their potential #1s: Henne, Hart, Long, Woodley, Branch, Hall, etc.
Carriker might fall to Round 2, and he'd be a huge steal then. The Falcons have a lot of options in Round 1, and we won't know a lot until we see where they finally end up in draft position and which juniors come out. Because IMO, this seems like a very average year for seniors, with only a few that really stand out. This draft will probably be made or broken by the juniors.
