See, we say this now, but I guarantee you if the reverse happened (Kid fighting and hurting Shanks, Law losing immediately), the reaction would be entirely different, with people saying that it entirely proves BB is the endgame then.
The reason why people are having a hard time with this is because very few people can actually believe Shanks has strong endgame vibes.

‘Just ask doflimingo, katakuri fans .
I never seen kaido fans get into panic mode when luffy solo Kaido and actually beat him in final attack like other fans of other series. Normally they accept it , this guy lost to this guy. And move on .
‘I never seen Moro fans make excuse for Moro to lose goku like muh plot armor .
