I don't know....I just don't really like it when the anime completely changes the perception of events that happened in the manga. After watching that I wouldn't be surprised if an anime viewer came to the conclusion that Sanji couldn't beat P1 without the RS considering one of his stronger DJ moves was ineffective against him
but then again it's not the first the time the anime does stuff like these so no sense in dwelling on it. With regards to Luffy/Holdem, the anime adheres to the events of the manga as Luffy did use a red hawk on holdem so no complaints there.
