5. 1978 Pittsburgh Steelers
There were obviously many great Steelers teams throughout their great dynasty of the 1970s. However, this is the one that rates as the best. The Steelers posted an impressive 14-2 record that year, and everything just seemed to come together for the team. The defense was the best in the NFL in terms of points allowed per game, as opposing teams averaged only 12.2 points against them.

On the other side of the ball, the Steelers were in their prime. Bradshaw manned the controls with a host of dangerous weapons at his disposal. Franco Harris was effective as always, grinding out 1,082 yards rushing. Lynn Swann led the team in receiving yards. There’s not much else to say other than this was an all-time great team that delivered on its potential to win the Super Bowl. They did so by defeating the Cowboys 35-31 in a shootout. Bradshaw took home the MVP award, and the ’78 Steelers were cemented in NFL history as one of the best Super Bowl teams ever.
