Also, John Andretti was officially considered a Busch Series rookie of the year contender for 2006, even though he is a Winston/Nextel Cup veteran.
ROTY favorite Lamar was released early from his ride at KHI while leading the standngs. Eventually, the ROTY came down to a fight between NEXTEL Cup veteral John Andretti and former USAR Pro Cup driver Danny O'Quinn Jr. Eventually, O'Quinn, despite being released for one race to prepare David Ragan for 2007, he still managed to hold off Andretti to win the title by only a point. Another preseason favorite and 2005 NCTS Rookie of the Year, Tood Kluever, struggled in his transition to the Busch Series. Another USAR driver, Mark McFarland, had an up and down year and was replaced by Shane Huffman. Joel Kauffman and Chris Wimmer made bids for ROTY, but were released from their rides. A.J. Foyt IV, in his transition to stock cars, was released due to a Dodge development deal.
