For Keith Thurman, a win this Saturday night in Brooklyn over Shawn Porter will be the result of 20 years hard work and dedication after taking up boxing at the age of 7. The 27-year-old already has the WBA World welterweight title, and is one of a handful of men who could fill the void that Floyd Mayweather Jr. and Manny Pacquiao have left. Hearing about it and talking about it is wearing thin for Thurman. He wants to separate himself from the pack. He wants to go one better than Kell Brook, for example. The Brit took Porter’s IBF world title from him in 2014 with a majority decision verdict. but just winning isn’t enough for Thurman.
