Like any coaching staff, Bronco and co. had their issues and blindspots and weaknesses. But I
know he understood this principle. You can have a talent deficit at every position and still come out on top if you can force the offense to make the wrong calls with your personnel, alignment, and pre-snap motion. You can have a talent surplus at every position and still come out on bottom if the offense can always make the right calls based on what you show them. Same thing is true on the other side of the ball, too.
I wish I had a database that tied coordinators to plays, with info on personnel, alignments, motion, down and distance, score, time remaining, reads made, and the effectiveness of the play. I could calculate a predictability score for coordinators, and I'd be willing to bet there's a strong negative correlation between predictability and effectiveness. I'd also be willing to bet that the plays that were not well predicted (i.e. the opposing side made the wrong reads, or it was unconventional based on personnel, down and distance, etc) turn out to be the most effective ones. And then, if all that's true, we can probably have the computer spit out a flowchart showing "If you see this, call that" for both offense and defense. For our defense, it'd probably just be a single box that says "Mesh" on it, because that will probably eat our never-blitz zone for breakfast every single time... (I've read Hal Mumme once basically did this in a real game, and just called Mesh like 58 times in a row. Good thing we don't play him.)
