Yes but there wasn't a set precedent for it there.
In Dressrosa:
- There was a tournament centered on gaining allies
- Half the Strawhat was split, leaving only 5 actual strawhats to fight like 10 Doflamingo Executives (4 were defeated prior of the total 14 not including Doffy (Vergo, Monet, Baby 5, Buffalo))
- Not only that, but Kyros had a dedicated plotline to eliminate one of them (he eliminated 2)
- Robin was shafted out of a fight for that reason
Wano has been very clear cut:
- Only 8 Available executives vs Doffy's 10
- The entire Strawhat crew is present
- So far, 5 of the 8 executives have exclusive Strawhat fights, even Oda is doubling up on some.
- Only Drake, Apoo and Hawkins are available outside of those tied up that aren't strawhats. If none of these 3 fight executives, then its literally up to the strawhats.
- Finally, the arc has specified the old gen being taken out by the new, which makes Marco narratively not selected to fight these characters and win, unless Oda decides to make an exception.
