4. 1989 San Francisco 49ers
The 1980s 49ers were similar to the 1970s Steelers dynasty in that they fielded teams who dominated both sides of the ball and played exceptionally well together. This team may be the second-best of the great 49ers squads of the ’80s, but it deserves its spot among the list of greats nonetheless. You know how the story goes.

Joe Montana quarterbacked an all-time great offense that led the league in per-scoring with 27.6 points per contest. Head coach George Seifert had seamlessly taken the reigns from the legendary Bill Walsh, and the results were spectacular. Jerry Rice was well, Jerry Rice, racking up 1,483 yards receiving. Roger Craig was once again stellar on the ground, rushing for 1,054 yards. His prowess as a receiver out of the backfield in the 49ers’ West Coast offense cannot be understated as well. When this team got to the postseason, it wasn’t even a question if they’d win the Super Bowl looking back. They smoked the Denver Broncos by a score of 55-10 and Joe Montana became the greatest playoff quarterback ever – at least until Tom Brady came along.
