Having been too young to ever see guys like Glover play in person, I have to admit that it does put me at a disadvantage.
That being said I believe that that Suh is still the best DT I've ever seen play the college game. He has a great combination of power, athleticism, and a capable set of hands. He was able to do things against offensive linemen that I've never seen in the 10 years that I have closely watched football.
Unless somebody wows me more than Suh in the next 20 years, he would still be my pick for the best interior linemen 20 years from now.
