I don't know what Bute wants to do. Play with him a little while (5 or 6 rounds) and the finish him? Finish him as soon as possible? Take no risk and stay on the outside? We'll know in a couple of hours.
I only recognize one champion in that division and thats Pavlik. All others are contenders. He may have a belt but he's not the recognized champ
Anything but an impressive performance with a win by stoppage at the end will be not good enough. Bute needs to show an improved defence, a better jab, more precision and, generally, more of a fighting spirit. I predict Bute KO 6.
