The Buffalo Bills have to be the most cursed franchise in sports. Not even just American football.

Going to 4 straight Super Bowls in the 1990s (even losing all of them) doesn’t make you a snake bite franchise now when something doesn’t go right

If that's not snake bitten, then I don't know what is. What about 13 Seconds and the Music City Miracle?
