To Win, or Not To Win... That is the question?

Thoughts on Jeff Burton not moving Kyle Busch out of the way for the win... I know running another driver over to win a race isn't the way it should be done, and I agree. But in this instance, we're talking about BRISTOL. I mean, When your wheeling around half-mile bull ring, and you're faster than the guy infront of you, and ping is almost impossible on the outside.. Why not use your bumper?!
