I'm actually a 5'8 165 manlet, so there.
Yeh, the HWS have got the ability to do that, but they don't do it all that often. For every big KO, we get like 5 HW fights where they tire out in 0.5 rounds and then just sorta slob around the octagon for the rest of the fight.
Who are these tough opponents that Spivak and Jailton have fought? Spivak being in there against Tom means nothing. He looked like the can he is. He got to fight him because the division is weak as piss. Looked like a can against Gane too. He's only beaten cans. Same deal with Jailton. Fought cans. People thought he was some grappling god because he literally laid on Lewis for 5 rounds, and Lewis has absolutely zero grappling. What an achievement. Then his shit-tier grappling got exposed by Blaydes.
And yeh, Rosa vs Aldana was amazing, but hey, if you think the Brazilian Blanket Jailton literally laying on fat, lazy no wrestling slob Lewis is entertainment, then I'm happy for you, because that's the sort of shit the UFC love to put on for main events.
