Carroll became just the third coach in the history of football to win a National Championship in college football and a Super Bowl in the NFL.
Carroll won a piece of two championship while coaching the Southern Cal Trojans from 2001-2009. He split a national title with the LSU Tigers in the 2003 season and won the BCS national title in 2004 when his Trojans dismantled the Oklahoma Sooners. He nearly won a third in 2005, but Vince Young led the Texas Longhorns to a last second victory. Southern Cal went 11-1 during the 2008 regular season, but did not make the title game while two other one-loss teams, Oklahoma and the Florida Gators, did.
Johnson was replaced in Dallas by Barry Switzer, who led the Cowboys to a championship in 1995. He also won three national titles with the Oklahoma Sooners in 1974, 1975 and 1985.
