That a massive NT is essential in the 3-4. That couldn't be further from the truth. Ask any 3-4 coach and they'll say an athletic, quick NT is more beneficial.
My best memories of when Payne was healthy was his lateral movement along the line of scrimmage, making plays on RBs cutting the sweep inside (thats a big IF the OLB is keeping contain).
Big, fat tackles like Gilbert Brown are more suited for a 4-3 where tackles are used to take up the 3 interior OL. In the 3-4 all three DL need to have the athleticism to make plays, not just be a bunch of Siragusa's out there.
Not bad for my first post
