What you'd call okay, I'd call mediocre.
I think he will be a solid player, but at a high #2 pick, I'd like a guy with a little bit of a higher ceiling. Unless Rag turns out to be a HoFer, I think his role in this defense is and will always be easily replaceable.
That being said, he wouldn't be the first player to defy the film and come out like an entirely new player (Darby).
