So, over at http://www.allleftturns.com/  he wrote up an artice and included a video of the incident, and seems to be saying that busch is at fault for keselowski spinning just before the donuts he did for celebration.

watch this video, and it happens at the 4:07 mark. I'd like to know what you guys think.

Because it appears to me that Busch just wasn't expecting the 09 car to turn right into him. and even if he had been, it doesn't look like there was much he could have done. He went high to drive around junior and his friends little celebration, because he was mad, and he knew he had the best car on the track if he hadn't gotten spun out near the end.
