While he was originally scheduled to work a high profile match against the Undertaker at the event, there are those backstage within WWE that are pushing for Brock Lesnar to be moved into a program with Batista at Wrestlemania 30 instead.
Those backstage within WWE believe that it is all but assured that the Undertaker will be working a high profile match against Brock Lesnar at Wrestlemania 30 this year. Management wanted a less physical opponent, but opted to go with what they view as the biggest draw.
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.
