Yes, Canelo has been jumping from one weight division to another. And even when he jumped to 175 pounds he was still able to handle himself well and even scored a great knockout victory against Kovalev. So I don't think Canelo has made this decision without taking into consideration how much weight he has to gain to be able to face Makabu. If he makes it to the scale, I think he can also handle Makabu well and could even bring him to the canvas as well. But 175 to 190 has 15 pounds in the middle. That's a big amount of weight Canelo has to gain.
Based on the body built of Canelo it wouldn't be hard for him to attain the 175 pounds requirement for the Cruiserweight division and yeah for sure he and or his team wouldn't allow jumping from one division to another if they know that Canelo isn't capable of. Maybe 190 pounds would be a bit challenging for him on how to attain it but somehow I think we shouldn't have to focus on it since Canelo has already a scheduled upcoming fight against Makabu.
Exactly, one step at a time, if Canelo could win here, he can get some fights with the other champions on the same division. This guy is really up to a challenge, I mean, he wouldn't be in his position now if he does not keep pushing himself to his limit and I believe he has not achieve his limit yet since he is fighter in a heavier division and fore sure a more challenging division than his past divisions.
I'm sure he will win this fight, the odds difference is very convincing that even is Makabu is a natural heavy fighter but Canelo is more talented as a boxer. The opening odds pretty much tells everything.
