Maybe i'm wrong but that is what i'm thinking.
I would not be suprised if talks of a fight between Crawford will be called off and Manny will be fighting Mikey Garcia.

Please don't make it happen, this is a big fight and we don't want to see Manny fighting an opponent lower that what Crawford has achieve. This will be a big fight for Manny and if he wins, it will help him to be considered as maybe a GOAT in boxing, that if he continues to fight.
Who likes to see Manny fighting GGG if in case he will successfully defeat Crawford?
I guess there's no doubt that Manny could defeat GGG if he prove that he can beat Crawford.
Of course, Manny will not fight at the current weight of GGG, it will be a catch weight like they did with De La Hoya and GGG will be lighter but Manny will still be faster, that if GGG will agree knowing himself he will not have the same power. AFAIK, based on the articles i read, these 2 are friends but for the sake of money and entertainment, I guess they'll give it to the fans.
GGG vs Canelo
GGG vs Manny.
These are the fights I like to see.
