I don't necessarily agree. Liu can counterzone just fine, for one thing. The knife/fireball trade is not in Kano's favor at all. On top of that, Kano does not have a good punish for flying kick. B1 doesn't work, standing jab doesn't work, up ball doesn't work.
He can cancel that into MB Bicycle Kick which is +2 on block. The fireball cancel pressure has strings that it can be done off of to make it uninterruptable and each repetition pushes you back.
Kang's d3 has low profiling properties that can cause his b1, a mid, to whiff.
It's true that his overhead only causes a knockdown, so that isn't too bad. But he can throw, which is a viable mix up once you're conditioned to try and duck the throw for a punish, he can do his low string instead.
It's not an easy match up.
