No he wouldnt own him like Sanji remember Zoro is stronger than Sanji so Doffy would mid/high diff Zoro U_U.
No he's stronger then sanji but by portrayal not that much he's also slower then sanji and cannot fly... While his reaction speed is somewhat better then sanji it's not enough law got mid diff by Doffy and I rank law at the very least half a tier higher then zoro... So yeah he would get fodderized by Doffy
At best zoro strength should be paralleled with gear 2 except with the feat with pica it pushes him in between gear 2 and 3 neither which does much to Doffy
As u can c u need both speed and power to defeat Doffy or even try to injure him.
Sanji (speed) failed.. zoro (power) would fail as well and the same diff ...
Luffy (speed and some power) failed but he got huge power up which mixes his gear 2 speed (somewgwt faster but no control ) and power of gear 3 (somewhat stronger ) to even fight on an injured Doffy lvl (abiet pushing him to edge)
Law who's (smart + haxxed) got a solid mid diff
Luffy g2/3 got low to mid diff majority of tht part of fight
No way zoro would do better then these 2 especially against a healthy Doffy he gets the sanji treatment cuz while stronger then sanji he is still in same category and is way slower then the guy so zoro would be taking more hits then sanji did..
