Gotta be one of his K1 wins, or fights he had in this sport when he was also in K1.
I can't choice between - Duffee, Spong, Hari, Saki, that dude he almost killed with a knee in DREAM, and also that dude who is the striking coach of NU, who also looked like a dead body after 2 knees.
Lesnar was fun too. It's impressive he was able to take so many knees.
I feel like current Reem is fun to watch, but he is trying more to not get hit than hurt his opponents. And it's of course the right thing to do, but I can only think of what Reem back then would be doing to those opponents. Instead of taking 2 rounds to finish someone with a glass chin like he did in his last fight, it would be fast.
