With the Patriots using a lot of the 4-3 front against the Jets, the common misconception that the alignment tells you the gap philosophy has risen its ugly head. It is true that in most defenses a 4-3 equals a one gap and a 3-4 equals a two gap, but not necessarily. In fact, the Patriots DL were playing a two-gap 4-3 against the Jets, as they usually do! It seems that some on this board and elsewhere think that by using the 4-3 the Patriots are playing the same one-gap 4-3 that is common throughout the league. If they were playing a one-gap 4-3, what BB calls a college 4-3, we would have seen DL avoiding contact with the OL, penetrating into the backfield, ends racing around tackles, who knows, maybe even some stunts and spin moves---there was virtually none of that. The DL took on the OL directly, playing two-gap technique. Of course there are always a few exceptions, BB's defense are never so simple, but the fundamentals of our defense are usually not changed between a 3-4 and 4-3. BB has said in press conferences that when they substitute a DL for LB, the responsibilities of the other 10 guys don't change much (of course there are some subtle yet important differences---I'd love to hear from some of the real experts around here about these). The only exception that I'm aware of was Super Bowl 39, in which the Patriots played a one-gap 4-3, actually using a 2-5 with LBs serving as the DEs (anyone aware of any other times BB Patriots' have played the one-gap 4-3 extensively?). This had to be one of the most radical coaching moves in the history of football, to use an unfamiliar philosophy and associated techniques in the penultimate game. This also had to be one of the worst blunders in media history because the announcers never mentioned it once! The media generally missed the radical move, probably because they made this same mistake---they are used to the Patriots changing alignments/fronts and miss the point that gap responsibilities are a far more significant change in defensive philosophy. I don't mean to dismiss the use of 4 DLs by the Patriots, I think it is a very interesting trend, but it is relatively minor in comparison to a shift from the two-gap to the one-gap, which would be a radical change.
