The fight was definitely a split decision, and it could have gone either way. Watching live, I bet it would be 2-1 Hunt and was correct. I watched all the decisions again, and changed my opinions on two of the fights. Silva won outright, and Arona did nothing worthy of a decision in a title bout anyway.
In Crocop-Hunt, Hunt definitely pressed the fight. This is expected since Crocop is a counter-striker, and was fighting against a much larger opponent with heavy hands. Had Crocop not turned his back on Hunt, he would have won the decision.
