I actually have the pleasure of knowing Sam as he's a customer at the store I work at and comes in from time-to-time with Kofi Janutah ( you can read about the goings on where I work here:
Today at GNC Vegas: ).
Sam is a Hell of a nice guy and funny if you read that thread. But more importantly he's a World Contender in Boxing's Heavyweight division and one of the most dangerous guys there. His loss to Wlad came at a cost as he knocked Wlad down 3 times in their fight. Sam is big (and in-person he's got all kinds of scars on his hands from destroying shit with his punching power) and hits like a fucken' wrecking ball. He's had issues with stamina and last time I saw he and Kofi, Sam was being yelled at to run every day (I even offered to run with him). lol Last I saw Kofi he said sam IS running in preparation for his next fight with James Toney who is notorious for coming to fights fat.
So enjoy this inside look at the Nigerian Nightmare, and grimmace at imagining taking his punches. It would suck BAD.
