From NBC SportsWorld: The toughest one to leave off for me was Rafer Johnson, a man I deeply admire and have written about at length. He is, of course, a better athlete than numerous people on this list, particularly No. 100 Eric Moussambani, who isn't a great or good or average or mediocre athlete. But, like with all lists, I wanted this one to tell a story. Rafer was left off.
