[QUOTE]Iprolate: I hadn't seen that whole transcript--thanks for posting it. What caught my eye was this: " You play different fronts, you play different spacings and you teach the techniques of your defense and that is what is consistent. The techniques that are taught in the different defensive systems, whichever ones you want to talk about, are consistent within those systems . And those teams go from a three-man line to a four-man line or a four-man line to a odd spacing line or overs-to-unders or unders-to-overs or over-wides or whatever you want to call it. They'll continue to play the same fundamental techniques that they've been teaching for the entire year , for the most part. I think that's what teaching defensive fundamental football is about.... There are techniques in terms of how to play your front, how to defend the number of gaps and the ways that the offense can attack you, particularly in the running game. So how you want to do that? In a normal set you have eight gaps - seven blockers and eight gaps - so how do you want to defend that? Do you want to defend it with seven people or do you want to defend it with eight? That's really what it comes down to. And every time you spread a guy then the defense spreads a guy, so eight becomes seven. Then seven becomes six. Depending on how many guys are detached from the formation, then that's how many gaps you have. You decide defensively how you want to defend them in the running game. Do you want to defend them with gap control? Do you want to two-gap? Do you want to try to overload the box with extra guys and play eight against seven or seven against six? Those are all the choices you make. With every decision, there's going to be an upside, there's going to be a downside. There will be advantages to playing certain things, there will be disadvantages to playing [them] . So every system has multiple coverages, multiple fronts to adjust to, different problems that the offense presents." The significance between defensive systems isn't 3 linemen or 4 lineman, but the concistently taught technique, and the philosophy of how you chose to defend the gaps in the run game. What's important about the Pat's "3-4 system" isn't 3 lineman (we regularly show different fronts), but the fact that lineman have to control two-gaps, and that the ends play a 5 technique. I don't know what the technical term for run containment is for LBs ("run containment?") on the eddge, but that's what we've done a good bit of in the past. That's why I think there's value in talking about the Fairbanks 3-4, the Arnsparger/LeBeau/Capers 3-4 "safe-pressure" 3-4, etc. What the two systems have in common is the gap control philosophy, but the rest is completely different. My guess is that we are shifting to a defense that that has single gap responsibility. Our player personel and (so far) training camp mean the defense will "continue to play the same fundamental techniques that they've been teaching for the entire year ."

This is too reductive. You are making the assumption that every play or most plays everyone is two gapping or single gapping.
On any given play you could have one player two gapping, and three players single gapping. Or two players two gapping, and two players single gapping. Or no players two gapping.
And every team, for the most part, teaches both fundamentaly, while some run one more than the other.
If you came out and ran nothing but double gap responsibility with three lineman you would get abused because the other team would adapt their blocking scheme rather quickly. How many gaps a person mans depends on the reads they make at the line and how the offense sets up -- I know, I played the position (DT/NT/DE). Some plays if the offense had seven men on the line you might be looking at two gaps from nose, but if they had seven on the line and no FB, you might be setting up under. That
is the essence of what is being comunicated -- by BB here.
Adding Albert Haynesworth will probably change nothing fundamental about the defense. Like everyone on the NE patriots since BB got here, he will do some single gap, some two gap. Only counting running downs of course, otherwise he is headed uphill.
He will probably fill the Seymour role, which wasn't primarily manning two gaps in run control, but often relied on help from his right to set the edge while he penetrated the line.
The idea that 34 teams double gap and 43 teams single gap is as mythic as the idea that the two systems are completely different.
