First of all, I'm a huge Alan Belcher fan, I was really hoping that he would challenge Anderson Silva for the belt. I think that would be a great match up and we'd see some fantastic striking. I was sad to see him lose.
With that said, I'm sure a lot of people were amazed at Alan Belcher's strategy against Yushin Okami. Instead of circling, he went backwards in a straight line until his back was against the cage. Instead of relying on his boxing, he kept looking for a headkick KO. Instead of doing everything to stay on his feet, he went for multiple (I forget if it was 2 or 3) failed guillotines. Instead of getting back up when got top position on the ground, he got dragged into a grappling game.
Is this because
A) He lacks fight IQ, was too confident and didn't notice that his strategy wasn't working and wasn't able to adapt?
B) He was too nervous, couldn't really execute his gameplan or pick up instructions from his corner because his mindset wasn't right?
