Not the same thing at all.
Pre-TS the SH's didnt even know what haki was.
Comparing it with Post-TS, after Zoro even recognizes Luffy's CoC on fishman Island makes no sense.
as far as know Zoro have very little understanding about CoC right now
he was never trained for it
he don't even know he have it
how the hell he should know he is using Ad.CoC?
Oda is not stupid to mention CoC randomly
guys just stop this
you CAN'T WIN this debate at long run.
let Zoro have his win ... there is VERY VERY VERY VERY low change of Zoro losing the CoC game
