King was saying he is busy in Chapter 1004:
King was seen as fighting alongside with flying gifters against Marco in Chapter 1005:
Marco wasn’t even panting, except for one time when he was trashing King + Queen at the same time.
Back to Chapter 1022. How Marco can move faster than both King and Sanji, if he was defeated? Surely not:
Notice how Marco moves after King and Sanji, but still ends up faster. He is far faster than King, not even close.
Kaido after defeating Luffy was panting;
Rayleigh while fighting with Kizaru was panting:
And Marco is not even panting yet:
He could keep soloing King + Queen, but he leaves King and Queen to Zoro and Sanji instead.
