While Las Vegas has spent decades pining for a pro sports franchise, the one sport that had long called Sin City home—boxing—slowly dropped off the radar. Enter Al Haymon and his Vegas-based Premier Boxing Champions promotion. Haymon, an enigmatic boxing manager and longtime adviser to Floyd Mayweather Jr., leveraged his huge stable of fighters—including champions such as Keith Thurman, Shawn Porter and Amir Khan—into a regular prime-time slot on NBC, CBS, ESPN and other networks. It’s the first time in ages that boxing fans have been able to watch high-profile matches on television without digging into their pockets. PremierBoxingChampions.com.
