Why should he be sorry for winning?

I just found this article featuring Jimmy Johnson on Scenedaily.com, and I just have to wonder is why should Brian Vickers be sorry for winning? Vickers responded to Johnson saying something like, "He knows that if I hadn't been drafting with him, he wouldn't have been able to pass Jr."
Yes, that response was somewhat cocky, but let's give him a break. It was his first win in Cup. Johnson, we know, would have done the same thing to win; he has done it before. Go Brian!
