#3 Ronda Rousey
Having Ronda Rousey as Heyman's client would undoubtedly help both parties involved. This would give Ronda a mouthpiece and maybe give her a chance to hone her mic skills learning from him. She's got something special in the ring and putting Paul Heyman in the same conversation as Ronda Rousey only furthers Rousey's chance to become something even more special in the eyes of fans.
Wrestling Observer reported "There has always been talk of Heyman and Rousey to be put together if Lesnar leaves, and actually it was something discussed before Lesnar extended his contract." Brock Lesnar reportedly extended his contract the same week that Wrestlemania 34 was to be held. So it's safe to say that Heyman and Rousey could've been something seen on WWE TV since April 2018.

If they ever decide to go with this pairing, it could be a nice change of pace for Heyman, and a nice change of pace for the fans seeing the first ever Paul Heyman GIRL.
