Sure thing as in hes gonna be a star or sure thing hes a lock to LSU?
I'm thinking its the first. Don't know if anybody would think of him as an all-time "sure thing" LSU locks when there are already committed players in his class and he isn't one of them.
And really, it's a good question. He's certainly considered the most sure thing of any player they've recruited since probably Peterson, I'd think...am I missing one?
The one thing is, RBs are notoriously prone to injury and that can change things drastically. Look at Lattimore.
I'd say Clowney was more of a "can't-miss" because DLs don't break down quite as often as RBs.
