Team Canelo dropping the belt was to be expected. His team just isn't interested in making the fight right now. Like I said before, GGG is 34 years old. They will let him age some more. I can see it happening in a couple of years. Maybe even late next year. What GGG has going for him is that he is the 2nd most popular middleweight behind Canelo. At 154-160, the "names" just aren't there, so its only a matter of time. It's gonna eventually be a situation where the best fighters in the division make the most sense & present the best option.
Canelo is in a situation where he's physically too big for the fights he wants/needs. At 140-147, you can make real good money picking & choosing. You can fight an over the hill judah, turn around & fight a Berto, oh there's a guerrero, how about algeri, let me fight a Brandon Rios, etc. ''
They are gonna keep this 155 thing going until they can't.
