How does Aaron Rodgers stack up against Bart Starr and Brett Favre in Super Bowl performances? After long searching, I found a site that had the play by play sheets from all the Super Bowls (it was a betting info site, imagine that). Using that data I was able to go back before the NFL started recording fumbles and fumbles lost (a key part of the Positive Impact Factor formula) and fill in the blanks. As it turns out, Aaron Rodgers had the best performance as a Packers quarterback in a Super Bowl. Rodgers' performance also ranks 18th best all-time Positive Impact Factor for a quarterback in a Super Bowl. As you might expect, Phil Simms' near perfect game in Super Bowl XXI was the best single game performance and Joe Montana had the best career Super Bowl performance.
