More than one-third of NFL teams have never won a Super Bowl

With three weeks to go in the regular season, the New England Patriots (22%) are the favorites to win the Super Bowl, according to FiveThirtyEight. It would be a record-tying sixth Super Bowl win for the Patriots, breaking their second-place tie with the Dallas Cowboys and San Francisco 49ers.

In all, nine franchises have won at least three Super Bowls, accounting for 75% (38 of 51) of all Super Bowl wins.

At the other end, there are still 13 franchises that have never won a Super Bowl. Those teams have combined to play 564 seasons during the Super Bowl era. From that group, the Philadelphia Eagles (19%) and Minnesota Vikings (13%) are being given the best shots to end their droughts this season.
