Brook is the unbeaten IBF welterweight champion, a survivor of a machete attack in 2014 when he was left for dead in a pool of his own blood and is finally at the end of a long summer in the Canary Isles where he piled on 13 pounds of solid muscle, probably across the top of his back, shoulders and in his thighs.
Brook is moving up two divisions, leaving his sanity in the lower weights and taking one of the greatest risks ever by a British boxer.
Golovkin is naturally stronger, taller, has longer reach and has so far varied just about every ending with a punch selection that makes connoisseurs of the old noble art purr.
Brook is faster than Golovkin, which is a decent keystone to start constructing a fighting dream.
Golovkin is no stranger to the weird side, a product of the last sunset at the Soviet system, a clinical learner who, as a professional, has studied the graceful movement of cutting horses to polish his own ability at shutting down a man’s ambitions under the neon.
