If he went to Top Rank I think there’s a good few fights for him. He could fight Rivas on the Fury Wilder 3 undercard, that would be amazing. Then fight Pulev after AJ brutally KO’s him.
Top Rank would work. If PBC ever plans to put on a boxing show again I think they'd be a good fit. At the higher end he could fight Luis Ortiz or Andy Ruiz. He could also fight more guys at the level he's been fighting at: Charles Martin, Adam Kownacki, Robert Helenius, Gerald Washington. Frank Sanchez has called Hunter out lately, he's not with PBC but he fights on their cards. And then he could check Ajagba if they ever feel like he's ready to step up.
PBC could work well for Hunter if they go via the IBF route: 1. Kubrat Pulev 2. Charles Martin 3. Oleksandr Usyk 4. Michael Hunter 5. Andy Ruiz Jr. 6. Robert Helenius 7. Filip Hrgovic 8. Joseph Parker 9. Tom Schwarz 10. Dereck Chisora Pulev is about to get his shot and Usyk will go for the WBO belt, most likely.
