When the Ravens punted back, pinning the Giants on their own 13, it was more or less over. It was still 0-0, but the grinder was grinding. Sure, in theory, New York could have won. That could have turned the game. I vaguely recall other plays that could have turned other Super Bowls for the Buffalo Bills or the San Diego Chargers.
History remembers only the clobberings that followed.
Throughout the playoffs, the Ravens were deliberately touchy about not getting proper respect. But there was nothing about their reputation that wasn't their own fault. They got whipped in the Miami mud in September and lost to Pittsburgh and Washington. They let Jacksonville's Jimmy Smith catch 15 passes on them for 291 yards, and let the Jets' Vinnie Testaverde pass for 481 yards. They went five games without a touchdown.
