Too weak evidences tbh
The fact Aokiji kidnapped Pudding just shows he can do the job with ease, since there aren't a lot of people who can compete with him for real.
He has nothing against Pudding as of now, he isn't an intentionally evil dude who would do something to her for no reason (like Vasco would, probably), he just captured her probably to support the goals of the crew he is in right now.
Aokiji is quite the womanizer actually
And to think Sanji will already beat someone as strong as Aokiji, who has much more reasons to be stronger than everyone in Teach's crew, including Teach himself, will fight Sanji soon? Idk... Seems too much
Oda would need to boost Teach and Shyriu's perfomances like crazy, just so we could say they are at least comparable to Aokiji
Aokiji fighting the Straw Hats as a pirate already seems weird enough for me, and fighting Sanji because he captured Pudding feels the same way imo
