I just watched the fight again and I can't help to believe that the judge that called it 49-46 Bones is well within his right.
I call it first round for Gus with his ring aggression and the takedown is the cherry on top.
JBJ took the center of the octagon in round two and stayed there the entire round. He did not do a ton of damage, but to me it felt like he pushed the pace and kept the fight where he wanted it in this round.
Third round Alex put the fight in his court most of the round. He did not do anything overly impressive, so I can understand if someone felt that the champ was not outclassed in this round. Nothing spectacular from either fighter, but neither of them backed down either.
Bones was a few breaths short of a finish in round 4. They must have come up with a prototype polymer in Sweden and implanted it into Gus' chin before this fight because the beating he took at the end would have finished most of the fighters I have watched. Good on Gus for living, but Bones earned that round with the late brutality.
Bones looked like a man (albeit a tired one) that knew he needed to win a round in the 5th. Gus was short on energy in the 5th, he kept moving, but nothing he did challenged Bones. He threw his hands out there a bit, but nothing Gus threw was going to cause any damage. Bones put some shots on Gus, nothing overly impressive, but more than Gus could muster, so it makes it 49-46 Bones in my book. Round 3 could easily go either way, but that still makes it 48-47 with the champ retaining the title.
I am no fanboy for either fighter, I just enjoy watching fights. There is no bias in this opinion, I feel the judges got it right. That said, I hope we see a rematch because this was one of the best fights I have seen in my life. Nobody loses if we get another opportunity to watch these two warriors get after each other again.
