You simply cannot say this for someone who was above weight and on Peds. Being able to absorb hits, not worrying about stamina, and having additional punching power compared to your norm allows you to approach a fight however the hell you want to.
Stop.
You're talking about something you don't really understand, because you haven't ever even fought 4 rounds of boxing yourself. Why do Americans always talk so much shyt out of their simple, self obsessed little brains?
I'm talking about skill acquisition and execution, Garcia has never had much variety in his punch selection, in that fight however, Derrick James was able to get him to use three and even four punch combinations that didn't utilise his left hook, and even punched with the straight right to the body and then the jab upstairs, both on the step. He'd never done that before that fight, and it was because of how James sets up counters and combinations in his mitt work, James uses mitts differently to most trainers.
That's different to retaining power and strength due to a sarm called Ostarine. That's a different discussion. I'm not doing a back and forth either, move on now.
