I would agree, but do we need to invest that heavily in one position? Before we took Hood, we also had many top-ranked defenses. During the Cowher era, we picked ONE 1st round DL (Hampton). The rest were mid-round guys (Steed, Aaron Smith), castoffs (Ray Seals, Kimo) and just fill-in guys. We did fine. Spending a #1 on each spot, in a position that doesn't do anything but occupy blockers, is excessive IMO.
Well, NT is the most important of the 3 DL positions in a 3-4 front...that is not the one that you want to skimp on.
