If you believe that he doped, what makes you believe he would stop after a slap on the wrist 6 month suspension?
If Canelo was enhanced the first fight you best believe he will be for this fight too. I'm not really considering PEDs in my evaluation for this fight.
Both have Iron chin, GGG probably edges Canelo in cardio, Canelo uses more footwork and movement in his defense, which is why his gas tank suffers. GGG was effective in marching forward with high output in the first fight, but I think Canelo is the more versatile boxer (can fight behind a jab, stick and move, focus on defense and throw selective power shots, even brawl a lil bit), and can adapt better mid fight.
First fight also proved the fix is in for Canelo, not saying Byrd was paid to score 10-2 Canelo, but their is favoritism towards Senor Alvarez. Hard to find a good bet for this one, but I settled on Canelo by split decision +540. Would be satisfied with anything nearly resembling their first fight. One of the best boxing fights I've had the pleasure of watching live.
