I used to really like Jeff Burton but, you're right, he's been irritating me lately too. I still think he's one of the smartest drivers out there.
As for today's incident, I initially thought it was definitely Burton's fault. Listening to Benny talk about the replay, though, I can see where Jeff's left tires reacted negatively to driving over that hump. Of course, he shouldn't have been that aggressive in practice...
