But I also remember feeling shocked that these were the men I’d assembled. These were the founding fathers of a multimillion-dollar company that sold athletic shoes? A paralyzed guy, two morbidly obese guys, a chain-smoking guy? It was bracing to realize that, in this group, the one with whom I had the most in common was . . . Johnson.
