Rampage, first round KO.
There was no way that was stopped early. Chuck was a zombie. That's the reason he was asking all the questions afterwords -- not because he thought it was stopped early, but because he didn't remember what happened. If anything, Big John saved Chuck some brain cells by stepping in when he did. There was no way Chuck would have recovered from that, and Chuck agreed that he got caught in his interview.
He'll be back though, but I don't know if he'll ever be champ again (at least as long as Page and Hendo are around). I guess Rampage has his number in the ring or cage.
I thought the refs called good fights tongiht. Even if Jeremy Stephens didn't tap (which it looked to me like he did and then tried backpeddling out of it), his elbow was toast. He would have tapped again or had it broken. Another good stoppage by Big John in my book.
