#4 Brock Lesnar names his own opponent for WrestleMania
The best way to book a dream match may just be to have Brock Lesnar choose his own dream opponent. In this way, Brock Lesnar could potentially call out someone like CM Punk, who is a part of FOX at this time but is not really a member of the WWE Universe yet.
This could also be a very interesting way to bring in a big mainstream name from the world of combat sports like Daniel Cormier. The two men had a very interesting confrontation in the UFC and WWE would look to capitalize on their history to book a match between these two men, much in the same way that Cain Velasquez and Brock Lesnar tussled it out not long ago.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
Brock Lesnar could even call in someone else who's a part of WWE at the moment such as WALTER because a match-up between the two men would certainly be very interesting and not something the world expects to see at WrestleMania.
