Just to clarify, a "1-technique" defensive tackle is a one-gap lineman, not a tackle designed to eat up blockers. That applies more to 0-technique (nose guard in a 3-4) or 5-technique (ends in a 3-4). In a 4-3, the tackles are in the 1 and 3 positions. Traditionally, those tackles are "one-gappers" that penetrate and are more disruptive.
Iowa's defense is a bit of an odd-ball. It runs a 4-3 cover-4 scheme, but doesn't scheme the traditional responsibilities (not always a good thing). Even though the tackles play in the 1 and 3 gaps, Iowa generally asks the tackles to eat up blockers to allow the linebackers to fill the gaps. The staff also tend to recruit and play ends that are stouter but not as athletic as one would expect in a 4-3 scheme. The end result is that you keep everything in front of you, but, at the same time, you're essentially eliminating one playmaker (the extra LB in a 3-4 scheme). That puts more pressure on the safeties to play the run, which, in turn, puts more pressure on the corners to cover deep. That is why most teams attack our defense with short routes to the flat. Those zones are going to be open since the corners have to play off.
When Iowa has poor defenses, it's almost always due to having a combination of tackles that are not disruptive, and ends that are not explosive. You need one or the other. When we have good, experienced LBs, a lot of those issues can be "covered up," but, when we don't, the line gets exposed.
So how will it work out when we have NFL DE's, Questionable DT's and completely unproven LB's?
