rya I hate to say that you have it all backwards. Dana and the UFC cant lose. Brock looked dominant against Mir, before making a rookie mistake, which was expected by many. Against Herring, he dominated a solid fighter with a lot of experience. Should he beat Randy, he flys into the marketing stratosphere. As was said here by Mullet, Brock hits quite a few different markets for the UFC, and he sells himself exceptionally well, I guess being in the WWE paid off for him.
He is a very skilled athlete, who is still learning. However, his natural skills, size and strength should get him through
