When the Admirals do get defeated, what order do you think it will be? Also who do you think will end up defeating them?
If I had to take a guess, I would say the order of defeat will go Kizaru>Kuzan>Aramaki>Fujitora>Sakazuki.
And if I had to guess on who will defeat them, I would say Luffy for Kizaru>Maybe a SH Ally for Kuzan>Sanji for Aramaki>Zoro for Fujitora>and Luffy again for Sakazuki.
Defeated for good or just beaten in an arc? Because the way I see it none of them are down and out until the final war. Anyway, EOS I see Fujitora sticking around.
Might see Luffy get the better of Kizaru in this arc, there's a chance, but I doubt it. Also there's a chance Teach is on Egghead since we saw the corner of the Sword of Xebec a few chapters ago and, well... light vs dark.
If we're limiting the opponents to strawhats I think Sakazuki is the one most likely to be taken down by Luffy though. The one that looks most like a Zoro opponent is Aramaki given they both follow a green demon motif and Aramaki appears to actually be a swordsman at heart with a black blade. If we go by this then Kizaru is most apt for a Sanji opponent.
Anyway, I actually think the most likely scenario is as the final war plays out it's SHs vs Gorosei with some revolutionaries sprinkled in there and the other Admirals fighting unrelated opponents in various locations around the new world - some revolutionaries, some pirates and possibly a Marine in-fight (eos Smoker or Coby?)
