I've come to realize you see things in a slightly different light. True statement though.
OP is right to an extent, but maybe he doesn't really need to evolve at this point. There's a plateau eventually. The clinch guillotine or takedown, elbow smash will always be his bread and butter. Reminded of Tito when he was able to throw his weight around. I'd like to see him win by a standing KO though.
Thats how evolution works. You evolve up to the point where you are better at everything then everything else. Then you stop evolving. eg. Sharks. Wasps. Crocodiles. Jon Jones.
