That's true that Murata has the reach advantage, it's more like of an almost 5 inches reach advantage because it was a 12 centimeter gap. However, I don't agree in that particular statement that Murata's age is also an advantage compared to the 4 year older GGG at the day of the fight because that is just a short span and it's not that Murata have experienced and fathom GGG's ring IQ and experience when he was also 36 years old.
However, would you bet on GGG with very small odds and with this presenty old GGG who has some disadvantages against him? The fight also being in Japan is making me speculate that the referee and the judges will be in the yakuza's payroll hehehe. I would not be shocked if this fight ends in an upset split decision and Murata the winner.
If GGG wants to win, this fight should not reach the judges' scorecards, he has to beat Murata by knocking him out.
GGG has 36 KOs from 41 fights, I'm sure he can beat Murata by KO.
So if you want better odds, just guess which round GGG would stop the fight, or bet on ranges every 3 rounds.
I have a feeling 1-3 rounds gives better odds.
GGG winning by a knockout against Murata is not impossible, actually given his stats/record, the chances of GGG getting a KO is high and I don't doubt him at all that he can still do it this time around. Aside from that, he really needs to end this fight with an explosive finishing punch to attract more attention and put an end to the people who are doubting at his capabilities.
