Sorry, but I don't see it going any differently. Bigfoot is the only guy who can win two fights by brutal knockout and not look good doing it. I don't see them as fights he won, but more as fights they lost. Travis Browne got cocky and hurt his knee doing that stupid jump, and Overeem played around too much (knowing his chin doesn't hold up very well) and ended up going down for it (which is what he gets for acting like a cocky prick).
I still think if Bigfoot were to rematch his last two opponents, he would lose. And god forbid if he were to step in the cage with Cain again...
