Josh Pauls, Captain of the two-time gold-medal-winning US Sled Hockey team teaches us a thing or two about classifcation, explains why training on his own as a young player helped his development, and what it was like being a 16-year-old on a World Championship team. We also ask him about the fight that many people say is the gnarliest hockey fight of all time. (But, make peace, not fights.) Follow Josh on Twitter: @spudsUSA27
