Marco vs King still looks solid by the way the manga presented it to us. Let's see for further developments.
We now acknowledged that Yamato will attempt to buy some time before Luffy is up, which was obvious. Luffy might not be good enough to solo Kaido next and Zoro will have to help him out in that instance. Differently if Yamato and Luffy face Kaido together those "I got this" spelled words will come off as even more loose and Zoro will have even less reasons not to join over anyway. This matter of honor and faith is so overrated considering that they were tackling him together before Zoro was out, only then Luffy spelled those words.
