From everything I've read (my skreets: Rivals, AuburnUndercover, Scout & several GA Writers and twitter accounts, Rivals radio on XM...lol), universally Ray Drew is credited with being the hardest recruit to nail down to a school to be so late in his recruitment. As convfident as J. Lee, Mattews, Caldwell and others feel about him coming to AU, there are LSU and GA writers feeling confident about their standing as well.
In my opinion, regardless of what he's said, some actions of his (including a very good back and forth with a fellow recruit over Cam's situation on FB), he seems to be really into AU. So, I'd give us the slight edge due to actions over words.
Crowell has been a Bama lean for so long, that it'll be tough for him to swing out, but I'm not sure he wants to be second fiddle to Hart. He's been hanging with a lot of AU folks, including playing in the same backfield as Frazier on a game winning All-star game drive. He's been hanging out with heavy AU recruiters like Dismukes and other players.
For the same reason we should have an edge with Fulse, I actually give us the edge on Bama to swing Crowell. Just too much communication and relationships on the long term recruiting trail. Us having his last visit next weekend can't hurt either. If Drew commits on Friday, look for Crowell and others to secure a top 3 class on signing day. They'll all want to be part of it.
Just my opinion sifting through everything....
