The Diaz bros. are kind of an anomaly in that they sort of already have their legacies intact.
They're exponentially more popular than most fighters, they have a ton of name recognition, and they are very, very good fighters.
But at this point, they'll be remembered for what seems like doing everything in their power to undo said legacies.
Look at Nate. Not even three years ago, he legitimately became one of the biggest names in the sport overnight and in the time since it feels like he has purposely made a misstep at every fucking turn to the point that now he's back to being a footnote, for apparently no other reason than just cuz.
And the weirdest part is, if you look at peoples everyday interactions with the Diaz', say on Instagram or whatever, they legit seem like super nice and normal dudes, but as soon as they have to do any press or any sort of official function they can't seem to turn off the dude bro me against the world tough guy schtick.... It's really weird.
