Greg Biffle came to Roush Racing from the short tracks of the Northwest and quickly made a name for himself when he took the 1998 Rookie of the Year Award in the NASCAR Craftsman Truck Series. He went on to win the truck series championship two years later and captured the Busch Series Rookie of the Year honor in 2001. In 2002, Biffle became the first driver to win both the Craftsman Truck and Busch Series Championships. He accomplished a life-long goal in 2002 at Daytona with his first NASCAR Nextel Cup Series victory.
