I guess you could say Michael Oher as well, although he was probably an Ole Miss lock from the beginning.
I guess you could add Tebow to the list, even though he was probably Florida bound the whole time. I do remember how crazy it was for him when he was here though.
One who missed out on LSU was Luther Davis. Going way back I think of Marshall Faulk, Warrick Dunn, Major Applewhite, and Travis Minor.
I may have a slight issue with the wording of that... LSU didn't miss out on him so much as chose to go in a different direction. He would be listed with D1 Talent we didn't offer.
