I wouldn't trade up for him, but if he happened to fall I'd be elated. While he hasn't tested particularly well, his on-field play is very reminscent of Patrick Willis' at Miss.
People knock him for being "small", but he measured out in the same range as most other ILB who seem to skate by without that being criticized. If he finds himself in a good situation, I expect him to have a Lofa Tatupu-like impact. i.e.: People knew he was good, but for various reasons had reservations. In hindsight, they wish they had chosen him.
