When your favorite team has just blown a 25 point lead (not a reference to any game in particular), it's natural to wonder if it's ever been worse. Fortunately, Pro Football Reference has a list of the largest blown leads for each team and the biggest comebacks for each team (based on largest point differential at any point in the game) easily available.

Additionally, each team's row contains a link to the 50 biggest blown leads/comebacks in that franchise's history.

These tables can be found under the Teams section on the horizontal navigation menu.
