Otherwise, there wouldn't be so many videos and articles acting like it is innovative.

But, every single article I've read and every video I've watched in the last hour or so makes it look my High School Varsity BBall coach was teaching exactly the same thing 20 years ago. The only thing I'm potentially seeing that is innovative is that the defense has an assigned rotation scheme after the on-ball defender gets burned. So, rather than a pure reaction by the other 4 defenders (rotation throughout) there is an assignment for which guy picks up the ball handler and an assignment for the "peel" guy to clean up his own mess after the switch.

But, your explanation of the defense in this thread isn't convincing me of the innovation. Off ball sagging, proactive positioning, stop-the-ball help, and rotation by the 'peel' guy to pick up the help-man's guy aren't anything new from where I grew up playing.
