The green flag has fallen for the 23rd Brickyard 400. If you're looking for a favorite, Kyle Busch is the man to beat.
His recent history suggests no one can touch him: He's the defending race champ and finished second in 2014 and '12. He also has won the Xfinity Series race here three of the past four years.
Keep up with the action here all day.
