Dallas won Super Bowl XII vs. the Denver Broncos, 27-10. They completely dismantled our former starting QB, Craig Morton. Harvey martin and Randy White were named co-MVPs. The only time there have ever been 2. Ed "Too Tall" Jones easily could have made it a trio of honorees. It was the first ever indoor Super Bowl, played in the Super Dome in New Orleans. For many years it was the most watched television event in History.
