Why? Tucker was durable, yes, and Douglas fought a fantastic fight against Tyson. But Douglas was inconsistent and not nearly as good against Tucker as he was against Tyson, that's clear to see from both fight. So we are still left with that Tucker's best win was over someone who lost to Jesse Ferguson four fights previous. Not unreasonable, no. From what we know today it's also not unreasonable to say that his puncher's chance gives a decent chance against anyone. But he's still a bit hard to really asses, given that he hasn't met many quality fighters yet.
