Canelo is eerily similar to DLH. In a TON of good, great, and excellent fights but has his fair share of controversy and mulled performances. Canelo will likely be a fringe legend/ATG when its all said and done.
As far as the fight, anything less than a stoppage victory demonstrates a decline. GGG is locked in here too and his boxing is criminally underrated but he's never had good defense and everything about him looked bad against Murata. He was slower, less reactive, his body seemed more responsive to punches, and his power even looked a little less. Oh and GGG is moving up in weight and fricking 40 years old...
If Canelo can't absolutely wipe GGG I'd be hesitant to sign him to a long-term promotional contract.
