Aside from being utilized to help promote Brock Lesnar, who works a limited schedule, there does not appear to be much of a story line for Paul Heyman backstage. After being split apart from Curtis Axel and Ryback, management hasn't shown an interest in adding new guys for the former ECW owner to work with.
While management was not planning on giving him a big push or anything, there are some concerns that Curtis Axel is going to be held back by his tag team partner Ryback, who has secured himself a spot in the WWE dog house for a variety of reasons.
Curtis Axel will not be receiving a push in WWE any time soon. While management really likes him a lot, he simply was not able to capture the audience like they had hoped he would. The company still values him as a role player and wants him around.
