LAS VEGAS -- I met Shawn Porter in early 2016 as he was preparing to fight Keith Thurman, who was then the best welterweight in the world. Three things were immediately apparent, first among them being Porter's distinct physicality. He had fought most of his amateur career at 165.3 pounds. But even that 75-kilogram limit was pushing it for a kid whose alternate athletic endeavor was playing safety and running back in the formidable high school football leagues of northern Ohio. Porter was good enough to receive letters from California, Southern California, Virginia and Georgia Tech, but he chose boxing anyway.
