Well, go for it. For the record, ggg is a much better boxer, however the style clash 100000% favors jccjr.
With absolute ease, with his jab and jab only, catch him when he comes in over and over again, until he falls like a tree, a guy who blocks punches with his head, is the perfect opponent for GGG.
Wow, real bad fight for jr. Even in peak shape at 168/170 he still a heavy bag for ggg. Explain how jcc jr can make it competitive, that's the real question
I'd fear for JCC's life, draining yourself 20 pounds to have your head bashed all night by GGG, it'd be a brutal sight. Honestly, he might actually die lol if it was at MW
