re: LSU is a RB away from being scary.

Yeah, but you can't compare Brossette to CEH because Brossette is always running straight ahead. You may have a rare example of what you just said where he did something like that trying to get a first, but Brossette is a slasher and is always going forwards whereas Edwards-Helaire is always dancing trying to create, and in most cases he loses yardage because he's kinda slow, he's not Barry Sanders.
