Marino may have been the greatest passer in his youth, but he was one dimensional and nowhere near the greatest QB for his career. He was lucky to play for a coach who coddled him.
The 1985 Chicago Bears -- arguably the best team of that decade -- ran through the playoffs and Super Bowl by a combined score of 91-10 in three games. They went 15-1 in the regular season that year. Their only loss was to the Dan Marino and the Miami Dolphins. In that game, Chicago's vaunted defense gave up 31 points in the first half of the game.
Of all Marino's records, perhaps the one that stands out the most to me is one that doesn't get a lot of attention. In 1988 he led the NFL with 606 pass attempts and was only sacked 6 times during the entire season. That's an astonishing number.
