2012 was a story of injuries throughout the entire regular season, but most of the key players really got healthy for the postseason and the 2012 defense was pretty insane in the postseason. They allowed just 7 touchdowns but had 10 turnovers. They had an absurd SIX interceptions and five forced fumbles, four of which were recovered. They also ranked first in sacks and passer rating allowed. The Ravens defense was MONSTROUS in the playoffs and not a unit that should be written off because they missed most of their key contributors during the regular season. I still remember playing against Washington with like the third and fifth string inside linebackers or something stupid like that because the Ravens were so ravished by injuries at that point.
Also, while I agree that Flacco after his first two seasons was one of the greatest postseason quarterbacks of this decade, his first two years were abysmal. If we look at Ryan's first three seasons, they were mediocre, but not really Joe's first two years bad. However, these past three years, Ryan has been a standout in the postseason. He's been arguably one of the best players in the postseason, if he can actually make it. 2016 should go down as easily the greatest playoff run to not win the Super Bowl and would have arguably been up there as one of the greatest postseason runs ever if he had won. Sadly, Shanahan outsmarted himself.
