As far as WWE/UFC crossovers are concerned it appears Brock Lesnar is being used as a temporary rental player in WWE as his UFC days are over after getting brutally pummelled into submission his last two failed outings. Lesnar looks like a monster, talks like a monster but goes turtle very quickly after seeing how much sheer power and rage his opponents have for him. McMahon is salvaging Lesnar's reputation as a monster fake-wrestler by using him in a fake challenge with McMahon's son-in-law, Triple H.... The only other guy who'd have some nice cross-over power at WWE would be Chael Sonnen BUT NOT as an in=ringer fake wrestler. Sonnen's mouth and his ability to cut promos would be an asset as a WWE fake announcer - replacing the very tired Jerry Lawler or some of the other swill the WWE trots out.
