Welcome to reality. The odds are stacked against every team as there's a 1-31 chance that any of them win a SB in any given year. As it is, the rational you continue to use is terrible.
Of the list of the last 25 SB winners, 14 (56%) of them had both top 10 ranked offenses and defenses. Ok, great that’s what you want......but that’s what every team wants. It however is not a necessity as those remaining 11 SB winners (44%) were either:
a top 10 ranked offense with a below average ranked defense
a top 10 ranked defense with a below average ranked offense
or were thoroughly ranked mediocre on both sides of the ball.
So this notion that you continue to run with that a top 10 offense and defense is a requirement....or somehow increases the odds of winning a SB....or that it factors all that much in winning a SB is thoroughly ridiculous.
You also dismiss this teams' ability to put together clutch offense when they've needed to......like its not part of the championship formula. The Pats & TB started a dynasty & have dominated the last 20 years relying a great deal on clutch offensive performances when they had to have it. Eli & Joe Flacco have 3 SB rings between the two of them for being clutch at the right time. Nick Foles won SB MVP last year for being clutch when the team needed him most. Seem to me being clutch at the right time matters more than the rankings criteria you continue to use.
You're trying entirely too hard to not give BoB credit & truthfully, its just not that serious b/c everyone here acknowledges that the offense needs to get better.
Looking at past Super Bowl winners by DVOA (the year being when the season began):
2017: Eagles 8th in offense, 5th in defense, 16th in special teams
2016: Patriots 2nd in offense, 16th in defense, 8th in special teams
2015: Broncos 25th in offense, 1st in defense, 14th in special teams (just need a great coach amirite?)
2014: Patriots 6th in offense, 12th in defense, 5th in special teams
2013: Seahawks 7th in offense, 1st in defense, 5th in special teams
2012: Ravens 13th in offense, 19th in defense, 1st in special teams (the year Jacoby fumbled)
2011: Giants 7th in offense, 19th in defense, 15th in special teams
2010: Packers 7th in offense, 2nd in defense, 26th in special teams
2009: Saints 2nd in offense, 17th in defense, 28th in special teams
2008: Steelers 21st in offense, 1st in defense, 13th in special teams
2007: Giants 18th in offense, 13th in defense, 20th in special teams
2006: Colts 1st in offense, 25th in defense, 25th in special teams
2005: Steelers 8th in offense, 3rd in defense, 10th in special teams
2004: Patriots 3rd in offense, 7th in defense, 16th in special teams
2003: Patriots 14th in offense, 2nd in defense, 16th in special teams
2002: Bucs 20th in offense, 1st in defense, 9th in special teams
2001: Patriots 11th in offense, 13th in defense, 6th in special teams
2000: Ravens 22nd in offense, 2nd in defense, 3rd in special teams
So going back to 2000, we have 4 examples of an offense not in the top 20 winning the Super Bowl. In all those years, the championship team had either the 1st or 2nd ranked defense (Texans are currently ranked 7th in defense). There was also the Giants year where they won with the 18th ranked offense.
There was one year where a team won with an defense not in top 20, though two additional years with a 19th ranked defense.
