After thinking about it, I think this fight might've been fixed. Stiverne came in just to go the distance hence why he had the high guard up all night and stopped attacking when he rocked Wilder. After all you have Don King and the odds for Wilder by decision was +1000, the over 7.5 rounds +200.
I kid you not I had this exact same thought this morning. Anything involving Don King I don't trust. Stiverne was also very public about not liking his purse for this fight.
