Helio Castroneves's record breaking 4th Indy 500 win might be like Al Unser who hadn't won at the Brickyard since 1978 but finally won his fourth in 1987. Could the same thing happen to Castroneves? Castroneves was the first since Unser to win back to back Indy 500s and is also the only to win in his first two attempts meaning he is ready for a fourth.
