That's a big accusation. I don't know on what part Canelo cheated but their fight was intense.
Maybe you are reading speculations and controversies much rather than the technical side. I like to have their rematch too to finally closed the door. Better to place a bet on Caleb Plant if you don't like Canelo. The odds are attractive and worth risking a bet. Who knows upset will happened.
My statements are not based on any news article. I am a big fan of GGG and I watched both matches live. I was also following the scorecard provided by CBS Sports and other third parties. At the end of the fight, GGG was ahead on everyone's scorecard. Compubox had GGG winning 10 out of the 12 rounds. But to our surprise, the judges scored the fight in a different way. Dave Moretti had GGG at 115 and Canelo at 113. Don Trella had it 114-114. And the surprise package was Adalaide Byrd, who scored the fight 118–110 for Canelo. I believe that Byrd was not watching the same fight everyone else was watching. Even if it was a close fight (which I am not going to agree), how can anyone have a score of 118-110?
