He definitely won't have an immediate impact with the Giants, see the Wilson experiment, but I'm starting to like him more and more after watching the JPP highlights of 2011. HE SEEMS LIKE AN EXACT CLONE! Other posters have made the point that Van Noy had 13 sacks and Ziggy lead the team with 8 QB pressures so although he hasn't had the hard stats, he definitely made a presence. Too bad he won't be there anymore.
Van Noy had more Sacks because he had more free shots at the QB as a Blitzer. Easier to get to the QB when the guys up front are dealing with the lineman and U have to beat a RB or TE
