That's actually the only "exceptional" quality I see. Watch Smith's "dip" against Fluker (RT) for a sack. Von swoops like that (albeit much faster). Most players can't do that.
If Smith can keep his speed, and develop the rest of his game, he could become a force to be reckoned with...but I think that will take a couple years (if ever).
