From the Elias Sports Bureau,
No team with an offense outside of the top 25 has won the Super Bowl (-49ers),
And no team with a defense outside of the top 25 has won the Super Bowl(-Pats,-Pack,-NY),
Which would eliminate all but these teams:
( How cool
would a Texans/Saints
Super Bowl be! )
Another: No team whose QB led the league in passing has won the Super Bowl.
Heard on Mike & Mike.
No 8-8 or worse team has won two playoff games(-Broncos)
No team with rookie QB has won SB
