It was definitely a fight worthy of a replay watch. I thought the decision was correct. DC had maybe the 2nd round but then he just clocked off and wasn't busy enough. He allowed Jones to play his game and ended up just stalking him around the octagon for the rest of the fight while Jones palmed him off. Occasionally he got in some great uppercuts, but he just wasn't working hard enough near the end, and Jones looked like he could have counter-punched him for a few more rounds. One thing about DC though - he has a chin of stone. A couple of those elbows would have stopped or hurt other fighters, but DC seemed to just shrug them off.
I didn't have a particular problem with what Jones did at the end. As has been said, fighters must protect themselves at all times. It's not a good look, but this was never going to be a respectful fight after all of the lead up. It appears the bad blood between these two might actually be real.
I really didn't know who I wanted to support in this one, as DC seems like an absolute dick, but Jones has lost that humble nature that gained him fans early in his career. The LHW division is starting to lose it's shine IMO and MW is becoming more the showpiece.
That said - Enter the Mauler.
