I find myself wondering about improvisation vs. execution. The two don't have to be exclusive, but they can be different mental skill sets. It would seem that there is an argument to be made that Saban's process places heavy emphasis on precise execution.
If the goal of HUNH is to 1. limit substitution, and 2. limit systemic adjustments before the snap, this puts more decision making responsibility on individual defenders. As I understand it, both Leach-type passing offenses and read option running offenses are based around the idea of having relatively few plays within which there are numerous options. Whether it is novelty (which is defeated over time with acclimation) or a persistant strength of these schemes, it would appear that these schemes demand a type of decision making on the part of defenders which is more like improvisation and less like a systemic decision tree. (Again, not saying that the two are exclusive.)
I've heard mention that our defenders look slow. I'd put forth that while one element of this could be anatomical phenotype, it could also be that they are being put into a position that requires a kind of decision making which is uncomfortable. In uncomfortable situations one tends to think slow, and if one thinks slow, one moves slow. If Alabama defenders are routinely bigger and faster in raw terms, cognitive disruption becomes the only strategy to minimize this disadvantage. Like guerrilla warfare, a smaller force could not hope to compete in conventional terms with a (conventionally) superior force, so they must change the rules of engagement to have any chance. In improv comedy/acting, there's a frequently used phrase about "getting too much in my head" in which the performer is overthinking each decision during performance, to the detriment of his ability to act. Is there something about this sort of scheme (which, from the highly trained systemic viewpoint looks like to lack structure) that gets our defenders in their head and leads to playing that bit slower?
So...presuming that there's something to this, how does one modify the Saban process to develop more of the sort of "chaotic" decision making capacity (preferably without significantly sacrificing the systemic decision making)? Both types of thinking are skills and can be developed. The two are not mutually exclusive. But I find myself wondering if the successful adaptation to Saban's process is this sort of cognitive "chaos" that emphasizes quickness and flexibility and the ability to be comfortable in that (seemingly chaotic) environment.
Then on the far end of this spectrum is the sort of thing raised by Heart of Darkness or Apocalypse Now: following the guerrilla war analogy, at what point in response to this do your "methods become unsound"?
