There is no doubt that the Cowboys of the 1970s -- Super Bowls X and XIII -- are the greatest teams to lose a Super Bowl. Both clubs lost to the Steelers, who were clearly the greatest team of all time and the only team EVER to win 4 Super Bowls in 6 years. How can I prove these two Cowboy teams were the greatest to ever lose a Super Bowl. Because these Cowboy teams won two other Super Bowls in the same exact decade -- one of them crushing the Dolphins just before the Dolphins perfect season! What a great Cowboys team: Staubach, Pearson, Too Tall Jones, Charlie Waters, Howley, and the rest. They would have won 4 Super Bowls in that decade if not having to play against the greatest combination of offense and defense in NFL history: Terry Bradshaw, Lynn Swann, John Stallworth and Franco on one side. Mean Joe Greene, L.C. Greenwood, Dwight White, Jack Lambert, Jack Ham, on the other side. All Hall of Famers or soon to be so (Greenwood). Nobody else could beat that Cowboys team. They proved it. They beat the Dolphins and made them perfect the following year. They beat the heck out of the "Orange Crush." They just ran up against the buzz saw known as the great Steelers... Now, as to who is the worst team to ever win a Super Bowl, the answer is this: The worst team is the only team caught cheating in the Super Bowl, the team who knew the plays before they were called, the team who ruined a great team known as the "greatest show on turf," and who won their Super Bowls by 3 points at the last minute. Those Patriots teams would have been crushed by 3 teams of each of the following: (a) the 49ers, (b) the Cowboys, (c) the Raiders, (d) the Packers, (e) the Steelers and (f) the Redskins. Imagine Joe Montana in 1989 going against the 2002 Patriots. It would have been a massacre.
