The trilogy between Canelo and GGG will still happen even if the latter will lose his fight against Murata. The reward money is reportedly something that Canelo won't resist. It's an easy big-money for Canelo knowing GGG will be considered as weak if he loses against Murata. The problem is if GGG can't beat Murata, what face he will show to Canelo. GGG instead might back out, not Canelo.
But our topic won't be reached into GGG losing the match. Fair and square, I can't see something special to Murata that he can use against a much more powerful GGG. Knock Out or Decision, GGG will win their match and I will give a 90% for that to happen.
1st: Yes, their fight will still happen even if GGG will be defeated on his fight versus Murata, if ever. But surely their trilogy attract many viewers as that won't be interesting anymore because we can already predict the exact outcome even if the fight is under negotiation.
2nd: Please provide some link that somehow show or tells that the reward money is something Canelo won't resist as it was an easy big money because I'm searching it through internet and I can't find it. Anyway, Canelo cannot really resist this time but it's not because of the money but because he signed a two-way deal that's saying that in-order to fight Bivol, he too should go for GGG after Bivol. So, a trilogy is really inevitable.
In order to make the fight attractive, they have to win both of their fights and they have to win it in a decisive fashion to attract the boxing community for their trilogy, a loss with anyone of them, casts a shadow on their capability to give the boxing fights a fight better than the two previous fights, legacy and huge money are at stake if both fighters come out fresh from
wins.
