i dont know, seems to be formulaic
2000 - Yes, Rams were top 6 in both categories.
2001 - Yes
2002 - Pats ranked 24th in yards allowed per game, 6th in points per game. Of course, the Rams D that year was 3rd in yards allowed per game, and 7th in points per game. Safe to say better D did not win this year
2003 - Yes
2004 - Yes, Pats had great D that year, although Carolina was top 10 in both categories as well.
2005 - Yes, although Pats and Eagles were ranked right next to each other in both categories, also both in top 10 for both.
2006 - Yes
2007 - No, Colts were outside top 10 in both categories, Bears allowed a lot of yards per game but were ranked 3rd in PPG.
2008 - No. As much as we play up the Giants front 4 and their feared pass rush, Pats D was ranked above Giants in both categories.
2009 - Yes
2010 - No.
2011 - Yes, While Steelers were ranked ahead of Packers, both were top 5 in both categories.
2012 - No, both D's were not that great this year.
2013 - No, 49ers were top 5 in both categories, Ravens didn't even make top 10 in either.
2014 - Yes.
2015 - No. Did you really highlight the Pats D this year beating Seattle's D?
Note that I was pretty much just checking against Azeth's highlights or non-highlights to see if a "top D"/better D of the two teams won the SB.
As far as his year to year, I count 8 right and 8 wrong. Your memory isn't that great Azeth.
Now if someone wants to do the leg work to compare a great D vs. a great O, that would be great. I remember them trotting out the stat when the Top D plays the Top O that the Top D is up like 6-1 or something in SB's. But that's just #1 v. #1.
