Which NFL franchises never to have won Super Bowl are closest to title breakthrough?

Interesting article and thought it would provide good discussion.

Bengals come in at 12 out of 13, just behind the Bills.

Quote:12. Cincinnati Bengals (0-2): After five consecutive one-and-done playoff appearances between 2011 and 2015, they've regressed, losing nine games each of the past two seasons. Yet coach Marvin Lewis remains, incredibly, despite an 0-7 postseason record and a team that regularly lets its lack of discipline trump fairly significant talent. Not much to indicate a sea change is forthcoming, though the players do deserve credit for a strong finish to 2017, when it seemed like Lewis was certainly on the chopping block.
