What I think being overlooked more than anything is AJ never looked right when he got in the ring with Ruiz before the fight started. AJ looked like he wanted to be elsewhere I've never seen him look that way before a fight.
Rabbit in the headlights is how i described him on the night in this forum He was totally switched off / elsewhere
Definitely not a lack of heart. You dont get up 3x and have no heart. He also got off the floor to beat klitschko in a gruelling battle. I agree with the analysis that he was clueless and couldn't adjust. That was the biggest problem but not the only one. Lesson learned: dont underestimate anyone in the top 10 and work on your stamina in case you cant end it early. At least, I hope he learned it.
