Boxing is a sport as much about entertainment as it is about fighting, which is the real reason Muhammad Ali is considered the greatest of all time. Some fighters have the charisma and story line that make people queue up to watch them in the ring, and others simply go to work. Glen Johnson is the latter. Even his manager calls him a "lunch-pail champ." For the past 20 years or so, the Jamaican-born Miami resident has quietly been going about his work, racking up nearly 50 wins and an IBF light-heavyweight championship along the way. His brightest moment came in 2004, when he knocked out Roy Jones Jr. — long considered the best fighter in all of boxing — at the FedEx Forum in Memphis. Still, Johnson is hardly a household name, and even now he has to convince promoters he'll be a draw if they put him on a title card. The 40-year-old's biggest fight left is against time. In April 2008, Johnson lost a controversial decision to WBC champ Chad Dawson (a Showtime viewers' poll immediately after the fight showed 80 percent thought Johnson won), and ever since then, Johnson has been arguing he deserves one more shot. His February 2009 victory over Daniel Judah at Hard Rock Live just might give Johnson that chance.
