[Alas Babylon!]

I'm unaware of any mutual problem between the Bills and Vikings

Both have been to the Super Bowl four times and lost each time.

So one of them would have to win, which means only one would be the all-time loser.

[WhoisAlanGreenspan?]

Right. But my point was all three have 0 Super Bowl wins.

Since 1960 Bills & Vikes 10 division wins to 1 for the Lions.

Vikes playoff wins/losses 20/29, Bills 14/16, Lions 1/12.
