No. A big punching, supposedly ATG level MW being unable to stop career WW Kell Brook is not a good look imo.
This is what's expected with fighters in his own division, but now he's put himself in a position where if he can't KO a WW moving up, now there's even more questions then before. Bottom line is he needs to KO Brook.
All GG has to do is win the fight in style. No one can measure the guts of a fighter. Brook might be able to soak up some punishment who knows. That IMO is the biggest question concerning the fight. Can Brook take it? Brook clinches good and shows a good jab, but he's going to have to gain GG's respect early. He's going to have to land some bombs and I hope the crowd gets into the fight and pushes that adrenaline to the max.
I didn't want this match, to be honest. I predict GGG by KO/TKO. I really respect GGG, but if he is not capable to defeat Brook easily, then he doesn't deserve all hype around him. Let me remind you - only decent Brook's opponent was Porter.
