Title: President, NFL Players Association
Pro: During his 24-year tenure as head of pro football's union, secured a larger share of league revenues and free agency rights for his players.
Con: The NFL has one of weakest unions in sports and player contracts are non-guaranteed. Has come under fire for his callous treatment of retired players: "I don't work for them," he told a newspaper. "They are not union members and they have no vote."
