Yeah I don't get the whole safety thing, he doesn't have the range for it IMO. I think it might just be talk to try and boost his stock.
He can def play as a pure safety but I'd bet anything on it whoever drafts him will move him around to max out his value. Guys who can do that are all the hype right now. And he can do that.
I don't see safety either. As i mentioned in another post, Cravens scored lower than Ragland in most of the lower body explosion tests (vert, broad, shuttle) and his hand timed 40 was 4.69 compared to Ragland's 4.72 laser.....which means he's actually slower than Ragland since hand times are usually a minimum of 0.05-0.08 faster....sometimes even more than that.
