I've finally found the video.
Watch the last 150 for yourself.
I wouldn't put it in the Huddle category as he wasn't celebrating but I think he had more in the tank and should have won. Sometimes I think guys are looking over their shoulders as they are all out (Chesererk for example) but I think he was looking over his shoulder as he wanted to do as little effort as possible with Worlds this week. What say you?
