Nonstop pressure, relentless pace, breaks and finishes guys. Gregor has only gone to decision twice in his career like Jiri. And the only way to beat them is basically putting them out like Mo did to Jiri or Lee did to Gregor otherwise they're on your ass like a honey badger and in your face the whole fight and won't stop till you or them is finished. Gregor is the rare kill or be killed grappler since many fight safely and coast on positions but he does the complete opposite. Jiri obviously is a wildman with his striking.
