Biffle could be first to win championship in all 3 series:

#16-Greg Biffle thought about it back in 2000 when he won the NASCAR Craftsman Trucks Series championship. What if he could move on to the Busch (now Nationwide) Series and win that championship? And, what if, after winning the 2002 Nationwide title, he could move on to the Sprint Cup Series and win that championship? Biffle, third in the Chase for the NASCAR Sprint Cup by a scant 10 points going into the Camping World RV 400 at Kansas Speedway, has a chance to become the first driver in history to win the Triple Crown. Biffle, 38, came excruciatingly close to winning his third different NASCAR title in 2005 when he tied for second in the Chase, just 35 points behind champion Tony Stewart.(Kansas City Star)(9-28-2008)
