Shawn Porter was a top welterweight contender who happened to have the right promoter which was why he became champion.

He lost to the best versions of Kell Brook, Thurman, Spence and Crawford. He beat good contenders/champions Ugas, Garcia and Broner but was never an elite fighter. Porter used high energy and mauling tactics.

George Groves said he either fought him or was in the same amateur tournament as him so he must and been a top amateur at the time.
