Key here is haki..we know that law is able to cut down vergo who possess incredible haki, so law's haki is more powerful than vergo. Law is strong enough to go a few rounds with DD but still ends up losing with DD almost not taking any damage (though at the start DD had fujitora's help). So we know that DD has unbelievable haki and he also has conqueror haki too. If zoro does indeed takes on DD, then we can finally know how strong he has developed his haki...so far he has only been cutting down weak opponents after the timeskip..can't wait for him to show off his true strength.
