I know most of these myself.
Let me rephase my statement.
There is no definitive buildup for who is to be Sabo's EoS opponent.
We know holy knights vs revolutionaries is built up. CDs in general vs revolutionaries is built up. But nothing individually for Sabo, these are meant for group fights.
We can speculate that Sabo can get one of the stronger holy knights or even may get a Gorosei fight, but we can only guess.
Only individual to whom Sabo may have personal grudge is Akainu, who is Ace's murderer.
But Akainu seems to have a grudge against Dragon, and Dragon may have been an admiral candidate back in his marine days. I prefer Dragon vs Akainu more than Sabo vs Akainu.
If you meant that there is no build up for who is going to be Sabo's opponent
individually, I agree with you. There isn't: as I said, Shamrock, Garling, Topman; all are good.
From that post I wrongly get the impression that you were saying that there was no build up overall, when in my opinion there is clearly a build up of Sabo vs Govevernment. The only question is who from the Goverment.
And I agree Akainu vs Dragon, in case, would be better. However, if we go using personal connections, there are reasons to say Sabo vs BB too, or idk, Loki vs Shamrock/Garling during the final war. So, I think the safest way in general is going by narrative more than personal grudges. For the same reason Law and Kidd got BM and not Kaido.
