"It's great. It means that I'm in his head and if I'm in his head, he's got to worry about us running through this Chase," he said.
"It's one of those emotions that boiled over and I felt like the way that we raced each other on the track was what champions need to do ... I talked to my dad about things and my dad was like, 'Well, that's rubbing. That's racing, son. That's how it works.' He just gave me that confidence to know and he's the one that taught me a lot about racing."
Busch stuck to the line he'd taken immediately after the row at Pocono - that it had started with Johnson swerving at him and that it was a move not worthy of a driver of Johnson's stature. "For me, I think the line is when he swerved at us," said Busch. "I think he said yesterday he was trying to break the draft. That's not a move of a five-time champion."
But he admitted that if the incident had been discussed between them in a less highly-charged place out of the public eye, things might have been different. "If we would have run into each other in the motor coach lot afterwards, the adrenaline would have calmed down a bit and there would have been a better discussion," suggested Busch. "He was really amped up. He felt that I did him wrong.
"The response that we got from different people this week and the race fans, they said it was exciting and that's what they wanted to see. That's the intensity and passion that our sport is built off of," continued Busch, adding: "This is a bunch of guys running stock cars in the southeast. This isn't open-wheel racing where we're supposed to pass each other clean and be leading by 10 seconds."
