Kell brook hasn't even established himself as the best welter in europe. He'd get mashed by pac liked jennings got done by cotto.
Kell will be lucky to win a fringe world title. His list of opponents is pathetic, 95% of them have about 2 stoppage wins in their whole careers. He is too upright, leans back instead of moving his feet and doesn't have particularly impressive power. He has improved and has quick hands, but I saw him dropped by a journeyman due to his poor defence and footwork and his opponents suggest that his camp know he is chinny. I don't expect him to even win a world title never mind be able to become great or challenge the likes of Pacman. Pacman would destroy him in the opening round.
What happened to the 'any slick african american fighter derails Pac's train' theory? lol finally come to realisation they all ain't got what it takes eh..hate to tell you, but kell brook has even less of a chance
