If you're talking about the Block O on the kid next to Saban, that's Jacoby Stevens a DB from Murfreesboro, TN (which is where I live).
His high school is called Oakland, and they use the Block O as one of their logos. It's funny, when people around town see me wearing OSU gear with a Block O, they sometimes ask if it's for Oakland High School.
The kid's been committed to LSU for quite a while. I'd be surprised if he flipped to Bama at this point.
