007, Phil, and Imperial have a point. Interestingly, our zone is not that difficult to teach. The basic Xs and Os are not the reason that it is so effective most years.
Complete Bunk. It is the same arrogance KU is demonstrating. This zone is difficult and not easily replicated. Let's examine your reasoning in more detail:
1. When you say other teams don't give the attention to detail or practice time necessary, blah, blah, blah. That suggests difficulty. It is the cop out that all the other teams give, "we would be just as good if we used it all the time". That suggests that there is a lot to learn and it is not easy (or else a lot of time wouldn't be needed).
2. "recruiting for the zone". Maybe now as we move into selector school status it is more of a factor, but this hasn't been the case for long. Offense has ruled. Otherwise how do you explain, Devendorf, Flynn, Harris, or even DC2.
But, yes, I do agree that (most of) the players are now being selected, in part, to play this defense. And it is taking the nastiness to new levels. But they have to be taught how to do it. Fab/Rak/MCW/(DC2) are all recent examples of McD zone recruits that still needed a least a year to learn how to play it. That does not suggest an easy system.
3. Adjustments and surprises are part of our zone. It is part of learning to play it. It is part of what JB teaches. Saying our zone is not that difficult to teach and leaving out the adjustments is ridiculous.
I don't know why so many people want to discredit the job that is being done. This defense just set NCAAT records for nastiness. It is no tavern league zone.
