Feel ya there. Unfortunately that very thing is what's opened this huge can of worms as to who's fighting Jack exactly. Like do you see those 4, or any combination of those 4 being the ones who bring him down? OR, like all other major fights in One Piece so far, is it going to wittle down to one on one? The internet is a-buzz about who this person should be:

Law: Needs to be redeemed BADLY, but couldn't beat Doffy alone so beating Jack alone wouldn't make sense

Zoro: Captain is officially at odds with the Yonko now, and logical next level of strength for him is defeat of a Yonko's lieutenant. Has yet to be challenged, or on that note even TOUCHED in the New World. However it isn't fair for Zoro to outshine Law to such a degree as a fellow Supernova, who has both a higher bounty than him AND is a captain.

Inu: Has ACTUALLY fought Jack at full strength, and knows what he's capable of. While he couldn't finish him, the latter could not either. Kyros has shown that losing a leg can mean next to nothing, though you have to imagine it still puts him at a disadvantage.

Neko: See Inu, but swap out Kyros with Shanks. It should be noted however, that Inu and Neko did not fight simulataneously, but rather switched off every 12 hours. So while it is impressive that Inu and Neko held their own, it is MORE impressive that Jack held his own against a freshly rested Inu/Neko every 12 hours while he himself only got more fatigued.

I would love to actually see Inu and Neko beat Jack together, and I think it would be awesome for Inu to be Neko's arm and for Neko to be Inu's leg when they need it. The pacifista and Moriah/Oz showed that team efforts shouldn't necessarily be out of the question, but things just tend to work out in favor of 1-on-1 battles
