Like Spam said, there has been no DT that has been as attractive in the draft since Sapp. Dorsey has the size, talent, work ethic and motor to be a sure fire first round pick but he has perhaps the best technique, footwork and he uses his hands better than any rookie I have seen at the DT position which makes him a sure fire top 3 pick. He plays with outstanding leverage, holds his ground even against double teams and if an offensive lineman trying to block him makes the smallest mistake Dorsey will make him pay. DT's typically aren't NFL ready right out of the draft and if they are they typically don't play at a high level their first year. Dorsey is an exception he was NFL ready last year but decided to stay his Senior year and plays the position like a 5 year vet. He may not be able to penetrate and get to the QB like Sapp did but he will be just as disruptive and will do it his rookie year.
Dorsey will change the ways offensive coordinators game plan against us. Ellis is not that guy but he will be an upgrade.
