Green Bay Packers – 2013
Some people like to pretend that Colin Kaepernick wasn’t a good player, at least for a few years. But the Niners’ quarterback put on a clutch performance in freezing conditions against the Packers. San Francisco stunned the fourth-seed team at Lambeau Field and progressed to the Divisional Round.

This was a tough defeat for the Packers to take because they showed a lot of heart all season. Aaron Rodgers bounced back from a broken collarbone and inspired his team to the playoffs. They also missed some other key performers and that ultimately cost them (via Reuters).
