Joe Montana had what many consider to be the best performance in Super Bowl history. In Super Bowl XXIV against the Broncos, Montana completed 22 of 29 passes for 297 yards and 5 touchdowns, with 1 sack for 0 yards. Jerry Rice was the biggest beneficiary, catching 7 passes for 148 yards and 3 touchdowns, in a 55-10 blowout of the Broncos.

Do the math, and Montana averaged 13.23 Adjusted Net Yards per attempt that day. Making it even more impressive is that he was facing a Broncos defense that allowed just 3.89 ANY/A to opposing passers during the regular season. That means Montana averaged 9.35 additional ANY/A relative to the average Broncos opponent. Over 30 dropbacks, that’s 280 Adjusted Net Yards of Value that Montana added. That’s the most in Super Bowl history, just ahead of what Doug Williams did two years earlier against the Broncos.

In that game, Williams was 18/29 for 340 yards with 4 TDs and 1 INT, and one sack for 10 yards. That’s an ANY/A of 12.17, but it came against a slightly tougher defense: the Broncos allowed 3.77 ANY/A that season. So Williams was 8.40 ANY/A better than “expected” against Denver, over 30 dropbacks; that means he produced 252 ANY of value in the Super Bowl.

Below are those numbers for each of the 128 passers in Super Bowl history. For Super Bowls prior to 1981, I had to use estimated sack data rather than actual, with the formula for estimated sacks being simply (Team Sacks) * (QB Pass Attempts/Team Pass Attempts).
