So its very important to hurdle their fight first, GGG against Murata in Japan, and then Canelo against the reigning LHW champion on Bivol.
And I agree that Canelo will be the A-side in this fight, maybe 70-30 in favor of him.
As far as I can see, even Canelo and GGG will lose their upcoming fight, the impact and excitement is still there when they faced for a third time. It's a fight that everyone anticipated to happen for a long. To settle everything and it seems it's now likely happening, a third match is necessary to negotiate.
Just seems concerned to GGG here how he can deal with the prime Canelo if he will lose to Murata that is not even in his league.
About the split, 70-30 split is too much. Canelo is too overrated if that will be the final split.
If both of them will be defeated in their respective matches before the trilogy then the excitement and interesting factor will remain and the fight will surely be pursued. However, if GGG will be lost to Murata while Canelo have won his fight against Bivol then I think there's not much to expect for the trilogy as it would clearly state that the trilogy will be in Canelo's favor but if the opposite happened then it would certainly generate so much hype and a trilogy will so much interesting and maybe the split would be even.
