10. Stephen Espinoza
While HBO ran for the hills when the investment of DAZN and ESPN caused mega-inflation in boxing, Showtime showed no signs of backing away from a fight. Espinoza made headlines when he shocked the world with a six-fight deal ($450m) for Floyd Mayweather in 2013. The pressure is now on for Showtime, though; Deontay Wilder’s defection to FOX Sports is a blow, but Espinoza has vowed to do better in 2020.
9. Frank Warren
Even after he walked away from Sky to establish BoxNation, the Hall of Famer was signing up young talent and taking a long-term view. It meant that when he agreed a big-money deal with BT Sport, he had a domestic stable the envy of many. It was the signing of Tyson Fury that turned into the dream move of last year, effectively ensuring Warren kept his seat on the top table, while in Daniel Dubois, he may have the sport’s next heavyweight star.
8. Todd Duboef
Often written off a merely Bob Arum’s son-in-law, Duboef is Top Rank’s president who makes the world’s biggest promotional company tick. Happy to leave the limelight to Arum, Duboef did the deal that brought Top Rank back to ESPN and has helped increase the value of Top Rank’s stable, making it a company that boxers seem only too happy to sign with, from young talent to proven names like Tyson Fury and Naoya Inoue.
