Saban targeted Vickerson in high school and began the recuiting process. Saban left for LSU and Vickerson later signed with Michigan State. Vickerson has the size and strength to play DT at the NFL level, but he is very raw and needs a lot of work to polish up his game.
He should be considered a "project". Kevin Carter and Traylor are light years ahead of him in all phases of the game.
With a lot of work, Vickerson could turn into a solid NFL lineman. But it's more likely that he will end up being a journeyman back-up. I wouldn't be surprised to see him in NFL Europe for a year or two.
Saban also coached Dolphin DT Josh Shaw at Michigan State.
