Oda view Legends/goal post (mihawk, shanks) highter than the other top tiers because of this they will never look bad and any top tiers the legend fight without restriction (illness, stabs) will look bad. Perfect exemple is ryukugyu vs shanks, rayleigh vs blackbeard and 100% hp garp vs kuzan. Shiryu like them is legend wank victim, but rest assured when he fight zoro you will realize that he is a beast and that garp wank was just that strong.
