Bouts from different eras can’t be ranked: Arum (Reuters)

By Mark Lamport-Stokes LOS ANGELES (Reuters) – Next week’s fight between Floyd Mayweather and Manny Pacquiao is expected to be the most lucrative ever in boxing but that does not necessarily make it the biggest of all time, veteran promoter Bob Arum told Reuters. The heavily anticipated megabout in Las Vegas on May 2 is projected to become the sport’s top-grossing showdown, pulling in close to $500 million in pay-per-view, but Arum says it is impossible to rank contests from different eras.
