Sanji has countless panels like those. None of us has enough time or insecurities to do that though. Moreover they are too much

Btw it seems like Zoro, Sanji or anyone else in the crew can't have moments in which he just talks sense or leads a group without being the VC

Of couse Sanji leaded a part of the crew sailing as a captain through the NW, spoke on equal terms with Capone, a captain, in Zou and in WCI, interceded with BM himself for Luffy and the others after they invaded her territory and during the escape from WCI Jinbe and the others behaved as his underlings but a couple of panels now and then (400 pr more chapters ago) in which he talks sense while Sanji does something else or zero panels with his half of the crew are good too
If Luffy were to die, the crew would just shatter.
If Luffy were to be captured, Zoro or Sanji won't take the command until they save him. They would just try their best together
