Toney is out of his element here. Plus , James isn't really a heavyweight, he's an obese middleweight. The one chance Toney does have , strangely enough, is a punchers chance. Coulture may be a top MMA guy, but none of them really have the ability to roll with a punch, not like a real pro boxer does. Most of the MMA guys fight with their chins up in the air. Chances are, he won't give Toney the opportunity to find that chin, but it would be Lights Out for sure if Toney can find a way to tap that mandible.
I seriously want to see him get pounded into a coma but can't help and hope he wins just because he's a former boxer and a big name in the boxing world. Not going to watch that rubbish though.
Guys font hold your breath for Toney he really has no chance in this. Couture will be going for the take-down right away and finish it fast(ala.Slice/Mercer) to make a hollow statement for MMA. Now if Couture does try to go toe to toe, then Toney has a chance and Couture gains back my respect win or lose.
