How do we measure a year for our favorite National Football League teams? More often than not, it’s disappointing if our team doesn’t win a Super Bowl, or at least make the playoffs. For some franchises, victory has eluded them so greatly that right now they’re really crossing their fingers for a 8-8 record by the last whistle.

It’s a tough thing to measure.

Some of the greatest teams in NFL history, however, never won the Super Bowl. The 1968 Baltimore Colts, for instance, went into Super Bowl III as 18-point favorites. They had dominated the opposition all season behind the arm of Johnny Unitas, and their defense held opposing teams to 10 points or less in 11 out of 14 games. And still, they lost to the upstart New York Jets and “Broadway” Joe Namath.

Success isn't defined by a championship ring, but we can quantify it. Which NFL teams in the past decade have been the best?
