I think arguing over who has fought the better opposition is kind of pointless, as I believe both guys can beat each others opposition (apart from Canelo, I don't think pac beats him but that's a whole different topic) and that is what makes his fight so intriguing. The two best fighters of this era, who can hypothetically beat everyone and the only test is the other guy. So instead of arguing and throwing insults we should have civilised debates and appreciate these two guys because a fight like this wont come around for a long time.
