The Detroit Lions and Buffalo Bills are two of the 12 NFL teams that have never won a Super Bowl. A third of those franchises have never appeared in the game, including the Lions. None have lost four straight appearances like the Bills.
The two Canadian-border cities have supported their teams through thick and thin. Detroit and Buffalo both dream of achieving the football's highest level of success -- so far, out of reach.
The two teams will meet on Sunday (4:25 p.m. EST, CBS) in what could be a preview of that elusive big game.
