Luffy has held off not only an admiral but more than half of The Gorosei long enough for everyone to get near the ships.
He has done more than enough to parallel Rayleigh in Sabaody and is the clear MVP of this arc
But one thing that should remembered is that Luffy is about to run out Gear 5 soon.
And now the attention is turning to The Iron Giant who will definitely hold off Saturn, Warcury, and possibly Jupiter, leaving only Mars, Venus, and the rest of the Marines to deal with.
This is the perfect opportunity for the other strawhats to have their own Sabaody moment where they show their growth while Luffy is reaching their location.
And now the Vice Admirals are finally getting time to shine meaning fighters like Franky & others will show their growth.
Franky & Bonney will deal with the first wave, then the others will eventually join in as well like Sanji, Nami, Ussop, etc.
And I'm sure Oda will give Zoro a moment with Venus and possibly give Sanji a moment with Mars as well.
