“If you have a goal and you’re patient enough and good enough, why quit until you get it?” That’s how former heavyweight champion Evander Holyfield defends himself against critics who say that, at 48, he’s far too old for boxing. Most remember Holyfield as the boxer who had his ear almost bitten off by Mike Tyson, when the two met in 1997. He still hasn’t thrown in the towel and, this Saturday, will fight Sherman Williams in West Virginia. If he somehow manages to win, his next fight could be for the heavyweight belt. And if he prevails in that bout? He’ll become the oldest champ ever.
