Roman would be eyeing for the Universal Championship post WrestleMania.
However, if Rollins wins and The Authority decides not to award Lesnar a rematch, he could be coming after Reigns, as taking him out of the picture or feuding with him might give Lesnar a shot at the title again.
Daniel Bryan is the reigning WWE Champion, courtesy of his new persona and illegal tactics.
Although it is rumored that he could drop the title at WrestleMania, considering that he retains, and Lesnar is not allowed to go after the Universal Championship, Bryan could be in sight for The Beast.
Ironically, Lesnar beat Bryan clean at Survivor Series last year. Thus, advantage Lesnar.
