When PBC made its debut in the Spring of 2015, their top names were Deontay Wilder, Adrien Broner, Leo Santa-Cruz, Keith Thurman, Danny Garcia, the Charlo twins and Shawn Porter.
Spence Jr. and Davis were still making a name for themselves. Mikey Garcia and Manny Pacquiao had yet to join the roster.
I think their plan was to make them all be PPV stars by getting their names out on network TV. All these guys headlined shows on Fox, NBC, CBS, ESPN, Sp!ke, Bounce TV and Showtime from 2015 thru 2019. As the year comes to a close that will have happened.
-Deontay Wilder vs Tyson Fury (2018; 2020) and Luis Ortiz (2019). A possible 3rd match with Fury may be scheduled before the year is up as well.
Adrien Broner vs Manny Pacquiao (2019)
-Errol Spence Jr vs Mikey Garcia (2019), Shawn Porter (2019) and Danny Garcia (2020)
Keith Thurman vs Manny Pacquiao (2019)
Jermell Charlo vs Jeison Rosario (2020)
Jermall Charlo vs Sergiy Derevyanchenko (2020)
Gervonta Davis vs Leo Santa-Cruz (2020)
2018 - One PPV
2019 - Five PPVs
2020 - Four PPVs
Only David Benavidez has yet the headline his own show yet, which I'm sure will take place in 2021 vs Caleb Plant. He's in the next group of PBC'ers with the mentioned Caleb Plant and other young champs.
