Namikazo Minato and his underestimation

[Blaze Release]

Actually from manga/series we only saw Minato face A once, and then, he would've kill him if B wouldn't have interfered.
I think that he could've take the both of them at once, it's just that that he didn't have any grudge against them.
Also not even 1/10 of Minato(as in his techniques) was released yet, so it's hard to tell if the current A would match him or not.

We did see one of their many duels they had, but as A said they had many.
He couldve killed A?, no he cannot. A chidori sphere left a little mark on A who was surprised, but also took a full blast from juugo from point blank range. A kunai wouldnt kill him. Taken both of them? no comment.

 

[Rock Lee 8 Gates]

i strongly disagree...

really his speed is amazing but he just uses his kunai after he gets behind someone but he cannot come close to characters with strong defense

 

[Kronos]

Sorry Man, I disagree

As you said, A wasn't at that level back then =)
He didn't have that lightning armor, or even if he did, on a total basic/weak level(at most).
