I don't think they are going to give a victory over Brock to just anyone. It is either going to be the next top face or next top heel. They wanted Roman to be the face of the company. Cena is slowly stepping back but they have yet to really establish the next "IT" wrestler. This is the way to do that, using Brock. What Brock did with Randy shows they want him to look like a monster so when he does lose, the person who beats him will look inhuman.
