This is a 50/50 only because GGG size
Does he has the balls to move up in weight? dude thinks middleweight is the heavyweight division
P4P in no particular order:
Ward - started as a super mw, moved up to beat Kovalev twice
Crawford - started as a lightw, kicking asses at light welter now
Loma - moved from fw to super fw
Rigo - started as a bw, moving to super fw to fight Loma
Canelo - started as a welter, fighting now at mw
Mikey Garcia- started as a fw, beat Adrien Boner at light welter
GGG - stuck in the mud, asking for smaller boxers to fight him
