Yes, that's the methodology. But it's based on a flawed assumption and plain and simple....bad math. The reason there are fewer plays on the short side (often including the Mike) is that IT'S EASIER TO COVER AS IT'S LESS TERRITORY. That set on the defense does NOT indicate an opportunity. It indicates that they have their defense properly balanced for the field position.
The maddening thing is this; how many times have they watched this on film and seen that it DOESN'T WORK!!! Yet...Kirk still insists we do it. (Yes, Kirk. It happened under KOK, GDGD and BF. It's the Head Coach that keeps it in the playbook)
Forcing the square peg into a round hole is it. Other coaches adjust based on the players they have and what the defense gives them. Not Kirk.
