The guy has had over 100 professional kickboxing fights and is trying out a new combat sport after already being KO'd 6 times in kickboxing (and losing 12 times). He hasn't been an active kickboxer since 2012 (2 fights in 2013 if you wanna call it 2013). Ever think that maybe, JUST MAYBE, he's aged, out of his comfort zone in the octagon, not used to different sized gloves because of 100 fights with bigger ones, and green participating in a whole new sport?
All that is a great recipe for him getting caught, and he obviously had no instinct on what to do when he was rocked and on the ground - that's inexperience. That's putting a guy with 2 MMA fights on a UFC card.
To everyone acting like kickboxing isn't effective; fuck off lmao. There are a shitload of successful MMA fighters that come from kickboxing backgrounds. You don't just get to erase their background and pretend they all "trained t3h MMA!11" exclusively once they do well, just like you don't get to shit on kickboxing every time a kickboxer doesn't. If a kickboxer does well in MMA, y'all call give credit to "MMA striking." If he loses, y'all try and say K-1 sucks. It's the fight game. Shit happens.
And if you don't like K-1, fuck you.
