CHARLOTTE, N.C. — If Greg Biffle could go back to Sunday, when he grabbed Jimmie Johnson by the collar and spun him around to confront him, he'd probably reach for the five-time champion's arm. And he would maybe ask for a private conversation rather than interrupting Johnson during post-race interviews. For the way it actually transpired, Biffle said, he plans to apologize to Johnson.
