Bro if we’re talking about a single basic punch, which what Big Mom was throwing and a Luffy tried to block in base, Luffy definitely should be able to block it.
My bad, figured that you were talking about me because I just said it.
And yes, Luffy is destroying both Zoro and Sanji, and it wouldn’t be close. You mention Fujitora, but he wasn’t even being serious. He would have crushed Zoro as well, and Luffy at the time. Come on.
Captains are notably stronger than their subordinates, that’s been a dominant theme of the story since the very beginning. And with each enemy, the gap between Luffy’s opponents and the next strongest has grown wider. The gap between a Yonko and their subordinates is massive, and Luffy is getting near that level. He would destroy Zoro and roll Sanji, and it wouldn’t even be close.
