The Green Bay Packers have won 13 NFL championships, which is the most in league history. The Packers won three (1929 to 1931) of those titles when the NFL did not have a playoff system. The other 10 occurred when there was postseason play.
Included in that is four Super Bowl titles.
The Packers have played in 48 postseason games in their history, winning 30 of those games. The Packers have also played in 10 NFL Championship Games, with the Packers winning eight of those games.
The Packers have played in five Super Bowls, with Green Bay winning four times.
I'm going to rank the top four postseason quarterbacks in the modern era of the Packers. I'm not going to rank the quarterbacks from the Curly Lambeau-era, when the Packers won three NFL titles (1936, 1939 and 1944) in the postseason. The quarterbacks then were Arnie Herber, Cecil Isbell and Irv Comp.
Those three were fine quarterbacks, and Herber is in the NFL Hall of Fame, but I'm only going to compare the postseason quarterbacks from the Vince Lombardi-era to the present day. Since then, the Packers have played in 43 postseason games, and only five quarterbacks have started for the Packers in those games.
I'm listing four of them. The only one I'm not listing is Scott Hunter, who played in only one playoff game, a 16-3 loss to the Washington Redskins in the 1972 postseason.
Hunter was 12-of-24 passing in that game for 150 yards, with no touchdown passes and one interception. You want to know something surprising? Hunter outplayed his opponent (Billy Kilmer) that day in some respects. Kilmer was 7-of-14 for only 100 yards, but he did throw a touchdown pass without throwing a pick.
Let's take a look at the other four playoff quarterbacks for the Packers, who combined, have won 27 of 42 playoff games, and also won seven NFL titles, including four Super Bowls.
