The Super Bowl is the test by which all NFL quarterbacks are ultimately judged. Rightly or wrongly, every starting quarterback's place in history is irrevocably tied to his success in getting to—and winning—the biggest professional sporting event on the planet.
Stats like yards, touchdowns, completion percentage and even wins are important. But when you're talking about defining a quarterback's career and legacy, step No. 1 is counting the championship rings.
That might not seem fair, but it's how success is defined in the NFL: Success is winning the Lombardi Trophy; everything else is different degrees of failure.
But then what?
Once a quarterback has led his team to the mountaintop, how do you differentiate him from all the other ring-bearing NFL signal-callers? How do you split hairs between all-time great quarterbacks? How do you pick apart a bunch of players who were all good enough to be the best?
