Was Brock in his prime when he fought Cain?
If not how would prime Lesnar do against Cain?
Or how about HW Jon Jones?
Or the greatest Fedor?
There this mythical aura about Lesnar on here.
I honestly think he'd lose to Cain 9 out of 10 times.
Fedor would be a close fight, just because of Lesnar size. But if Fedor tags Brock quickly it will be lights out.
As for Ngannou. I think Ngannou beats the shit out of him. Ngannou take down defence is a lot better.
Stipe would be a very close fight.
As for Big Nog he'd find a way to submit Brock.
Jon Jones would probably annihilate Brock.
And Tom Aspinall would beat Brock also.
Oh yeah Ubereem will always be a hard fight for Brock.
That's just my two cents, take it or leave it. lol
Lesnar beats a lot of HW's, bro, HW division is weak, even you fans kept saying it for years
Or to be serious, let's do the math here:
Brock Lesnar beat Heath Herring who beat Cheick Kongo the fight before that
He beat Randy Couture who beat Gabriel Gonzaga and Tim Sylvia the fights before that
He beat Frank Mir who beat Big Nog the fight before that (and did it again later) and beat Kongo after the Lesnar fight, and also he beat Cro Cop too (whom also got beaten by Gonzaga too)
He beat the finishing machine Shane Carwin who finished Gonzaga and Mir
He beat Mark Hunt who beat Roy Nelson, Bigfoot Silva and Mir the fights before Lesnar fight, and would go to beat Derrick Lewis
He only lost to Mir first fight in which he avenged it later, lost to best version of Cain whom was undefeated and Ubereem who played dirty and was kicking him in his diverticulitis
So that means if Lesnar in his prime since it's unknown if he really had one or not cause his career was so short lived, I'll mention HW's he can beat, he losses to always, and HW's that he can beat if they're not in thei primes
HW's he'd beat from any generation (even in their primes too): Derrick Lewis, Roy Nelson, Cheick Kongo, Ben Rothwell, Tim Sylvia, Andrei Arlovksi, Randy Couture, Frank Mir, Heath Herring, Shane Carwin, Travis Browne, Brendan Schaub, Matt Mitrione, Pat Barry, Josh Barnett, Mark Coleman, Rozenstruik, Tuivasa, Stefan Struve, Ricco Rodrigez, Greg Hardy, Augusto Sakai, Chris Daukaus, Jeff Monson, Kevin Randleman, Bas Rutten, Pedro Rizzo, Gan McGee, Justin Eilers, Mike Whitehead, Paul Buentello, Alexander Romanov, Juan Espino, Marcos Rogerio De Lima, Rodrigo Nascimento
HW's that he can only beat when they aren't in their primes but losses to them in their primes: Francis Ngannou, Big Nog, Cro Cop, Sergei Pavlovich, Ciryl Gane
HW's he'd have competitive fights with prime for prime: DC, Stipe, JDS, Blaydes, Werdum, Jones, Volkov, Prime Alexey Oleynik, Sergey Spivak, Sergei Kharitanov, prime Bigfoot Silva, Jailton Almeida, Marcin Tybura, Waldo Cortes Acosta, Rizvan Kuniev, Tallison Teixeira, Valter Walker, Mick Parkin, Shamil Gaziev, Prime Shamil Abdulrakhimov, Ryan Bader, Renan Ferreira, Oleg Popov, Valentin Moldavsky, Vitaly Minakov, Ante Delija
HW's that will always beat him: Cain, Alistair, Aspinall, Fedor
And that's all there is to say, hope that helps
