It’s tough to learn much from a quick knockout. In another universe, Gray Maynard clearly had the capacity to knock out Frankie Edgar. But that’s different from constructing ways to beat Edgar on an axis of consistency, or repeatability. That’s a bad example because Gray almost did knock Edgar out (twice no less!) but you get the idea.
Still, every now and then, a quick KO can teach us: less about what happened, and more about what it represents. It took 0:28 seconds for Cory Sandhagen to separate Edgar from consciousness. And what a separation it was.
