Lightest weight class that could beat a legit HW

[AndersonSilva23]

What a weird thread. Conor at lightweight could KO a legit heavyweight. I mean, the odds of him winning the fight would be almost zero, but he has the capability to do it. You really don't need to have power or size or strength to KO someone. You just need a perfect punch.
But if you want to go with something like even odds, Anderson Silva in his prime could have beat most heavyweights.

Would love to see Connor vs Mark Hunt.

Some lightweights are closing in on 200lbs. Anyone close to 200 or higher stands a chance with any HW given the right strategy/skillset.

155 - ~180-200lbs
170 - ~190-210lbs
185 - ~200-225lbs
205 and so on.

Some of these guys cut a lot more weight than you think. Hell, as a HS senior I weighed between 170-180lbs off-season but I wrestled at 143lbs. If a nowhere HS wrestling program can cut weight like that imagine what these guys with money and nutritionists can do.

Take a guy like Lyoto Machida: He fought at and won the UFC title at 205 with cutting little to no weight. He is naturally about 205-210lbs. When he dropped to 185, he dieted down to 190 without cutting any water, so again he was undersized compared to some MWs that start their cut from 220lbs.

So if Lyoto cut weight like some of these guys, he'd be a WW because his off-season weight is ~200lbs.
