CONCORD, N.C. — Kurt Busch thought he and Ryan Newman were friends. He's learned the hard way this week that he was mistaken.
    Maybe that's how it goes between drivers looking to lock down jobs for next year?
    Busch is once again in the starring role as NASCAR's resident villain, this time for a series of incidents involving Newman and his team last week at Darlington Raceway. It's led to a series of scathing remarks from Newman, who has accused Busch in various interviews of having a "chemical imbalance" and lying about why he ran into the back of Newman's car after Saturday night's race.
    On Friday, Busch offered his version of events for the first time. He seemed agitated about the entire episode, and characterized it as the kind of "WWE-type action" that fans enjoy.
    "This is good for our sport. This is WWE-type action," Busch said, snapping at reporters gathered behind his team hauler at Charlotte Motor Speedway. "This is fun. This is entertainment, right guys?"
    The drama comes as NASCAR heads into tonight's Sprint All-Star race, which is traditionally billed as no-holds-barred event with nothing more at stake than the $1 million prize.
