Statistical Advance: Analyzing The Food City 500 At Bristol Motor Speedway

Kyle Busch’s 2008 can’t get any better. Can it?

He’s first in the NASCAR Sprint Cup Series points, first in NASCAR Craftsman Truck Series and third in NASCAR Nationwide Series.

He picked up his first 2008 NASCAR Sprint Cup win last weekend at Atlanta – and the coveted 10 potential Chase bonus points that go with it.

And with a NASCAR Nationwide win this season, he’ll win at least one race in all three series for the fourth consecutive season. Only Kevin Harvick (2003) and Terry Labonte (1995) have pulled that “cycle,” and they only did it once apiece.

But the news does get better for Busch. He’s back at Bristol this Sunday, the scene of the first-ever race in the car currently used in every race this NASCAR Sprint Cup season.

Busch fended off Jeff Burton to win last season’s March Bristol race by a slim .064-second margin.

But eyes will likely be trained on those drivers a little lower down in the standings. After this race, the 2008 owners points standings will be used to determine which 35 teams are locked into each race (the first five races are determined by the final 2007 owner standings).

That could mean trouble for some notables – namely Casey Mears (30th), Jamie McMurray (31st) and rookies Sam Hornish Jr. (36th) and Dario Franchitti (40th).

Mears has a Bristol Driver Rating of 55.4 and McMurray has a 67.5 – neither of which are in the top 20.

Neither Hornish nor Franchitti have raced on the tricky Bristol layout – a place usually treacherous on rookies. For instance, last season the best finish in the March race by a rookie was David Ragan’s 26th.
