Canelo/GGG would be like Hagler/Hearns. It's my favorite of the two and would be way more exciting. Ward/GGG is more interesting because we haven't seen Golovkin pushed yet and this would certainly do it but it'd probably end up being a worse fight. Ward gets ko'ed by Kovalev.
I think Ward-Kovalev on paper is the best fight 2 legitimate P4P fighters in there prime. I personally feel both Canelo and Ward would likely beat GGG(with different degrees of difficulty), which is no slight but I rate them higher from what I've seen.
None KRUSHER vs The Steamroller is the only fight up there i want to see (Steamroller vs Ward first though - to give the many who doubt Artur a second thought)
Ward GGG but I voted Ward Kovalev. Only because I'm not sure if ward will ever fight at 168 again where I want the fight between him and GGG to take place.
MEANING, these dudes are going to come at each other with no backing up, bombs away. If reports from their sparring session told us anything... It's going to be crazy fun.
