You could easily fill out a list of 100 influential people in football’s history just with great players, coaches, owners and commissioners. But the NFL’s story ranges beyond the field and the front office, and pro football has been shaped not just by the stars who rule the record book, the X’s and O’s experts who cooked up its strategies, or the power brokers who turned it into the most dominant sport in America. There are also unorthodox, sometimes unfamiliar personalities who injected color into the game, rogues who worked outside the rules and brought disrepute, and figures from related fields—media, medicine, money—who profoundly transformed pro football, and our experience of it.
