"WhatIfSports.com used its free NFL SimMatchup technology (you could do this too!) to simulate the 42 Super Bowl champions against one another -- 100 times each. This means that each team played 4,100 games and 86,100 games were played in total. At the end, we looked at all of the games and ranked teams by winning percentage to find the top 10. This is the most accurate and thorough approach to answering “the question.”"
