In 2003, Richard Childress Racing set out to win the Busch Series Owner's Championship with their 21 Car sponsored by The Hershey Company's PayDay brand. Cup driver Kevin Harvick was tabbed to drive 15 of the 34 races, with development driver Johnny Sauter filling out the rest of the schedule. Harvick ended up running 19 races, with three wins and top tens in all but one race, and RCR became the first team to win an owner's points title with two different drivers. Since then, the presence of Cup drivers and teams has increased; RCR for example continued to run the 21 with Harvick as well as a full-time 29 car with Jeff Burton for the owner's championship, while the 2 car with Clint Bowyer won the driver's championship in 2008. Several other non-rookie Sprint Cup Series drivers, including Greg Biffle, Carl Edwards, J. J. Yeley, Denny Hamlin, and Reed Sorenson, began running the entire Nationwide schedule while also competing in a full season of Sprint Cup, even though on some weekends the two series competed at venues hundreds of miles apart.
