This is a fight I definitely want to see. Brook is a big dude for his weight, so he shouldn't be out-classed. That said, I still believe that GGG will win. I bet Eubank Jr is pissed now.
Brook and Tommy Hearns are the biggest welterweights I've ever seen. I've read Brook walks around at 175. Golovkin weighs about 168-170 on fight night. The weight will be close.
I'm picking Golovkin in 6. Brook doesn't have the chin or the skills to win. I don't even think he's the best welterweight. I Thurman is the best,but he's still a good fighter. He's undefeated and has a win over an at the time undefeated Shawn Porter,as does Thurman. His resume is thin outside of that win.
I know some might not like the match up but I dig it. Brook is better than Wade. He's a name in the UK and will bring a lot of attention to this fight and hopefully that will increase the publics demand for a unification with Saunders. Saunders has not been very keen on fighting Golovkin. It's not like it's any worse than Canelo-Khan. I actually rate Brook over Khan but GGG is better than Canelo.
