No he wasn't. First of all he acknowledged Zoro's power when he launched Hiryuu Kaen, second it's hardly a coincidence he triggered his Hybrid mode after Zoro had pressured him. He heavily contributed and I don't think Kaido likely simply did to make a fast job of the novae considering he was allowing them free shots earlier apparently, he did because of that but there's most likely a causal relation here.
Regardless Zoro put into play overall better feats than Luffy, regardless of their ultimate total power level.
