Bingo. The operative word in BB's philsophy is versatility. He has always put out various iterations of the confusion based versatility game. When they had the personnel to execute, players would go into three points out of two points and vice versa. DB's would switch positions at the snap, the Mike would always be disguised, and when pressure came, it would be extremely hard to read. There were zone blitzes, standard dog blitzes, standing stunts, and many mixed coverages. Diverse, versatile defense.
The reason the "Organized Chaos" concept is effective is because it exploits the design of the blocking. Typical offense is predicated upon finding the Mike and making a check for a slide. From there it is something along the lines of "RG: Peek at NT, read head-up backer, seal". If it is more evolved, the protection or blocking scheme is still reliant upon the vision of the offensive line. A lineman will sit in his stance (typically having better vision from a pass stance than a run stance) and read the defense. He will evaluate the potential moves the defense could make based upon alignment and blocking scheme. For example, a tackle will have to be aware of an end crashing across his face, pulling him inside to open the outside for a rushing backer. If the linemen cannot identify the alignment of the front, it significantly inhibits their ability to be alert to confusion. It takes the main advantage of the offense and puts it in the hands of the defense.
It's nice to see that the coaching again has the confidence in their personnel to play this style of defense. It's been a while since we saw BB get after it defensively, and this is an indicator of how good a defense they have. Fun stuff.
