(if the Lions and Packers were smart, they would tie Sunday's game and both teams make the playoffs)
That's why in round-robin soccer tournaments, they now play the last round simultaneously, so teams can't conspire like that.  The worst case was Germany-Austria in '90.  I've never seen it, but everyone knew it was a joke.  In pointy-ball football it'd be a little harder to collude that way for a tie.  But hating the Redskins the way I do, I'd be laughing well into the New Year.
