I briefly heard about the conspiracy theories, and was curious to see for myself. The Silva Weidman fight was entertaining. Watching the fight to its conclusion I didn't think anything was staged. I saw Silva quickly realize Weidman is not an easy opponent, and switch to playing head games. Weidman stayed focused. Then I saw Silva take clowning too far and get caught flat footed with a good hard shot, hard enough to knock anyone out.
But then Silva's post fight interview put everything in a different light. He appeared too much at ease with the loss, not wanting a rematch, quasi retiring.. such a loss takes time to come to terms with I think. My gut feeling is that he was prepared for the loss. We'll never know, but taking into consideration the interview, it does look fishy. It wouldn't surprise me if there was some big money on Weidman.
