Read my other posts. Fighting for fodder usually comes have a high diff battle that leaves the protagonists pretty vulnerable. None of then outside of Robin and Chopper are hurt that bad and it was done on purpose. Usopp is the only character that hasn't even done anything notable this arc lol.
Seriously, compare a fight like Franky vs Sasaki to Inu vs Jack. Im not talking about offscreening here, but the actual condition of the people who won. Inu is very clearly not in the same condition as Franky, if Neko is to go by. Yes they were beaten by Kaido, but I'd be convinced that they have nothing to do the rest of the arc BUT fight fodder.
With Franky and Brook, it's weird because they are not hurt. With Yamato, Jinbe, Nami and Usopp it's less so but they are all in conditions where they could theoretically fight more than fodder.
I doubt it's something as high as a Yonko (BM), but I also doubt it's something as low as basic fodder too.
