Two stand out -
In 1980 they hosted the New Orleans Saints and fell behind 35-7, but behind sophmore quarterback Joe Montana they exploded to 31 unanswered points for the 38-35 win.
In the 2002 NFC Wildcard playoffs the Niners fell behind 38-14 to the NY Giants but exploded to 25 unanswered points behind Jeff Garcia, Terrell Owens, Eric Johnson, and Tai Streets; they still had to sweat out a last-minute Giants rally but a field goal try was blown on the snap and a botched endzone throw, ending a 39-38 Niners win, the last in the playoffs for the club to date.
Oilers blew 32 point lead to Bills in the playoffs. Before tonight, the biggest blown lead in the regular season was the 28 pt comeback by the 49ers against the Saints. 49ers won. Bills won that playoff game.
Demi Lovato did make the biggest comeback that I know of. No one actually knows.
