#2 Aleister Black
Paul Heyman has been said to be a huge fan of Aleister Black and personally wanted him on the Monday Night RAW roster. This fills the WWE Universe with confidence that he will be used well on the Red brand. However, it will take a good few months to get the former NXT Champion to the main event level of the WWE Championship.
Black has been only wrestling enhancement matches for the time being and now that Crown Jewel is out of the way, WWE could begin to integrate him into storylines. Booking the Dutch Destroyer in a competitive program with an Andrade or a Buddy Murphy would really build him up well and give us some excellent matches.
After a few months of effective booking, Black would be a formidable opponent for Brock Lesnar. He could even be the one to take the title away from the Beast, in what would clearly be one of the best WWE Championship matches in the past few years. It is also well known that Lesnar's best matches usually come with smaller wrestlers, like Finn Balor and Daniel Bryan among others.
