And yet our run defense, which he should dominate, sucks. So in other words the greatest DT, which he is, can still be neutralized in the run game.
Again it comes down to his position. For years it has been stated that DE, LT, CB, and QB are the key positions. Last week we saw what happens when you lose a starting CB.... Dallas showed what happens when you lose a LT.
Heck, right now I would think hard if I would rather lose Donald for a game or Havenstein just because he would be tough to replace.
That's the key, you can scheme to get effective play without him at DT, but not so at OT or CB and certainly QB.
