Brook is a big welter and probably walks around at closer to 154. He isn't Nassem but he clearly has the potential to pile it on. He has much more ring sense than Khan and has real spite in his punches, he may go down fighting because his heart is certainly there, but I think Golovkin will be surprised how honest Brooks punches will keep him early doors. I can't see Kell having enough pop to keep GGG off down the stretch and it's very likely he gets stopped, but it's not a nailed on certainty, nothing ever is once they step through those ropes. It probably has as much to do with shutting Khan and the Eubank mouths shut for Kell and Hearn respectively as the wonga they will earn. Respect to Brook for stepping up without the diva bullshit and I see him giving a good account of himself despite losing and increasing his saleability on the world stage. Vargas claims and anyone else's of him bottling it will ring a bit hollow now.
