“WWE wanted Brock to win the fight.
Brock/Undertaker were supposed to have a confrontation at the post-fight press conference.
Brock didn’t attend the press conference because he felt he would be stealing Cain’s moment.
Undertaker was waiting at the press conference, and when he got word Brock wasn’t coming, he left.
When asked if the moment with Ariel, Brock, and Undertaker was planned. Brock’s close friend Paul Heyman simply said, “Ariel is always in the right place at the right time.”
Brock Lesnar is asking for Roy Nelson because he believes he is a difficult match-up and wants to test himself.
While Dana has said Brock cannot wrestle for WWE due to his contract. They are hoping Brock will be “the guest referee” at Wrestlemania in a match involving the Undertaker (and Wade Barett, if you really wanted to know who the other guy is).”
