Kiper:
Oklahoma DL Dusty Dvoracek struggled Tuesday. Ohio State center Nick Mangold got the best of Dvoracek in the one-on-one rush drills. Mangold had another great day. He has proved that he is not a finesse player. Mangold is strong and technically sound. He looks like he could move into the first round but will probably go in the second round.

DB Daniel Bullocks, Nebraska
OL D'Brickashaw Ferguson, Virginia

EDIT Didn't see this anywhere else, but this was posted for the previous day (Monday) by Scout, Inc.:
Ferguson stood out as clearly the most agile offensive lineman the North roster today. However, Ohio State OC Nick Mangold turned in the most impressive overall performance. Mangold has adequate size and feet to go along with his outstanding technique and explosive power. He is polished and should be ready to start as a rookie in the NFL.
