You clean I don't have any panels supporting my post yet you claim that GB lol difficult him even though the battle was off screen.
The difference between you and me is I know that King is missing part of his wing which would weaken him and affect us overall fighting style and strength.
Luffy is a mytical Zoan and it took him a week just to wake up. He still hasn't fully recovered.
The manga tells us they are still recovering and King took more damage than Luffy.
