Are the 1985 Chicago Bears the best single season team in NFL history?

I think that if you had to pick 1 team from 1 year that you would categorize as the best team ever I think it would have to be the 85 Bears. They had probably the most dominant defense in NFL history, a stellar offense led by Jim McMahon, Walter Payton and Willie Gault. Not to mention they were such a great team that they made a song, "The Super Bowl Shuffle", in week 12 of the regualr season, yes that's right the playoffs hadn't even started. They dominated almost everyone that stepped onto the field with them (except a lucky win by the Miami Dolphins) and shut out the first 2 teams theyfaced in the playoffs. Not to mention completely manhandled the New England Patriots in the Super Bowl, winning it 46-10.
