Many people have questioned Kell Brook's brains for wanting to step into the ring with, quite possibly, the most dangerous knockout puncher in the world, Gennady Golovkin.
Brook has been wallowing since winning his IBF welterweight title and failed to secure any top box office fights as champion.
He has had to step out of his comfort zone - two weight divisions out of it, to be precise - in order to get the top fight that he wanted.

Now he faces Golovkin at the 02 Arena tonight in London looking to prize away the unbeaten Kazakh's WBC, IBF and IBO middleweight titles.
While not many people have given him a chance, his supper middleweight compatriot, James DeGale, insists he is rooting for Special K.
"I honestly think it'll be a good scrap," DeGale told Sky Sports. "It's hard to look past Golovkin and hard to think that a welterweight is going to beat him but Brook is a very big welterweight and there isn't much size difference. Brook has come from good pedigree, is unbeaten and confident. If he moves his feet and uses his speed then he could give him trouble. Hopefully he can pull it off but Golovkin is a beast.
"You'd have to go with the favourite, Golovkin. I'm hoping Brook can pull off the shock though to become a two-time champion, 100 per cent."
DeGale hit the nail on the head early on: For all the people that have tried and failed against GGG - all 35 of them - it's hard to believe a welterweight will be the man to put down the knockout king.
Will Golovkin register his 33rd knockout in 36 attempts tonight?
