He said something really interesting concerning his loss in BKFC 56.
They asked him "what the difference was" between Bare Knuckle Fight Club and MMA (or boxing).
Alvarez said,
"You have to accept the fact you're going to take serious damage.
In MMA, you can get away with being 'an athlete'; in boxing, you can get away with 'being an athlete.'
In bareknuckle fighting, you have to be a fighter. You have to be willing to accept the punishment."
Dude was crazy to come up in weight and face a guy like Mike Perry (who annihilated the bigger Luke Rockhold), but Eddie did it.
Looks like they may even have a rematch.
Hespect.
