Am I the only one who doesn't care what weight he's at now? Or what weight he will be 24 hours out from the the fight? or what his and Diaz's re-hydration weight is come fight night?
This is what we know: Conor was prepared for a 155 fight when he was facing RDS, then two weeks out the Diaz fight was trying to be arranged due to RDS's injury, UFC wouldn't give Diaz the extra coin he wanted for cutting to 155 on short notice, so Conor said, " fuck it, weight doesn't matter, let's do it at 170."
He loses to a tough Diaz who was straight off a holiday 11 days before. We all know why this fight is at 170 again. Conor wants a clean reset - beat Diaz at the same weight they fought at the first time, with a full training camp, so there's the FULL reset on his loss. It's an ego thing. Logically, we should be seeing this fight at 155 seeing as Diaz usually fights there, can make the weight (most of the time), and is only one weight class higher than what Conor holds the belt at and has fought previously in the UFC.
I genuinely don't believe Conor is looking to push the fight at WW again just to use the 'well it's 2 weight classes higher than I usually fight' excuse if he loses again (because he used it the first time). Knowing the Conor we see in interviews, he's convinced he's beating Diaz, at the same weight, under the same circumstances, thus cancelling out his loss.
The guy doesn't like to lose and will do anything possible to eradicate any doubt about having an advantage in the rematch. Other specifics don't matter. Yes, Diaz is better suited to WW than Conor, has fought there for stints in his career with noderate success, and no matter how much 'functional' size Conor puts on, he's at a disadvantage wanting to fight Diaz at 17 again.
But he's got an ego and a blemish he wants to wipe out, and he's fucking determined to do it. Even if it's at the expense of his overall legacy. Who gives a shit what either weight right now. It doesn't matter.
