Tough to say.
Luke Thomas made a really solid point on Promotional Malpractice that in order to move up in weight correctly one needs to take 4-6 months to adjust to all the changes to have effective muscle (Ie: Lean, conditioned muscle vs. bulkier, less efficient).
I'm interested to see Conor's next foray at 155 for that reason alone. I think he needs real time to let his body adjust and really bought his own hype and thought he was invincible to the size factor.
I think his power transfers if he does that or isn't fighting a guy with a GOAT-level beard like Diaz
