I'm big time against trading something significant for Ryan Nugent-Hopkins myself. He would be just another #2 center here at best, middling around 50 points at most and not making any of our wingers better. We need someone better than that, although he would be miles better than Rask or Ryan, but so would most other centers in the league.
Yeah ... production wise he's only Rask-like, but with a more rounded game with less of the Cloak of Invisibility. That's a useful player, but only to a point. You don't sell the farm for a guy like the Nuge
