Casey Hampton, doesn't he play in a 3-4? If so, he is completely useless in this discussion. Brian Young isn't a space eater and doesn't draw double teams, why? Because that's Hollis' job. Young is the faster DT who can go and make plays while Hollis makes room for him. IIRC, Tommie Harris is a space eater, so again the comparison isn't apt. You know why those 3 have very few tackles? Because they are doing their job while a Brian Young-type is doing his: making tackles. You're comparing two different roles at the same position.
