Yes ofcourse, we can't neglect that the boxing industry is also business industry giving entertainment in exchange of money and that's how boxers are getting paid. In the same sense, they're bring the best events at the last option so that all fights before the main event will sure have people watching even if they're just there for the main event.
Canelo is also wise, before he does not want to fight GGG again because he already won and giving him another fight is a risky move to Canelo as he surely knows that among the boxers he have fought, only GGG has the capabilities to give him another defeat. Now, he is open to fight GGG again because he's already old and the risk are somehow minimized.
If Canelo is showing interest fighting GGG, I'm on the side of money matters.
Yes, GGG is no longer in his prime and the chance is slim, unlike before when he suffers that loss from Alvarez, he still
capable back then to fight back and try winning.
Now the possibilities are still open, just need to win both of the upcoming fights. Afterwards, they can discuss the deal
between them if they both take care of their respective fights.
