It's happened twice. Sort of.
Super Bowl XIV was held in the Rose Bowl in Pasadena. The host team was the Los Angeles Rams (although they didn't play their home games at the Rose Bowl), who lost to the Steelers in that game.
Then, Super Bowl XVIX was held at Stanford Stadium in Palo Alto. The host team was the San Francisco 49ers (although they didn't play their home games at Stanford). The Niners beat Denver in that Super Bowl.
Three Super Bowl teams have played in their home state:
2. Super Bowl XIV -- The Los Angeles Rams in the Rose Bowl in Pasadena.
3. Super Bowl XIX -- The San Francisco 49ers at Stanford Stadium in Palo Alto, California.
Three: The Raiders (Oakland and Los Angeles); the Colts (Baltimore and Indianapolis); and the Rams (Los Angeles and St. Louis).
Don Shula and Mike Holgrem have both taken two different teams to the Super Bowl.
