2002: yes, #7 defense. It was also the same defense that gave up 41 to the Jets in that playoff game. Chad Pennington went 19-25 for 222 yds, and 3TDs . The Jets also had 180 yds rushing as a team on 42 carries (4.2 ypc), and 2 more TDs. That's 396 yds of total offense. The Colt defense allowed the Jets to score 3TDs and kick a FG on 5 first half possessions, and 2TDs and a FG on 4 second half possessions. Yes, Manning played horrible, but the Colts had only 52 yds rushing as a team, as well; missing a FG and fumbling on the first 3 possessions of the game. Manning's 2 ints came after the game was long over.
2005: yes, the #2 defense. It was also the same defense that gave up 300 total yds on 68 plays, and 21 first downs to the Steelers in that playoff game. Rothliesberger was 14-24 for 197 yds and 2TDs; and the Steelers also rushed for 112 yds, and another score. The Steelers scored 2 TDs in their first 3 possessions. Manning was 22-38 for 290 yds and a touchdown; and only got 58 yds rushing as a team. Yes, the D created two turnovers, including the fumble that led to Manning marching them into FG range, and Mike Vanderjagt missing a 46 yd FG to send it to OT...Adam Vinatieri doesn't miss that FG.
2007: yes, the #1 defense. It was also the same defense that gave up 411 total yds to the Chargers in that playoff game. Rivers was 17-23 for 312 yds, and 3 TDs. San Diego also had 99 yds rushing as a team, and another TD. Manning was 33-48 for 402 yds, 3TDs and 2 INTs. Indy had 44 yds rushing as a team.
2008: yes, the #7 defense. It was also the same defense that gave up 357 total yds to the Chargers in that playoff game. San Diego had 167 yds rushing and 3 TDs on 33 carries (5 ypc). Indy had 64 yds rushing on 22 carries (2.9 ypc). Manning was 25-42 for 310 yds and a touchdown.
2009: yes, the #8 defense. It was also the same defense that allowed Drew Brees to set a Super Bowl record with 32 completions on 39 attempts (that's 7 incompletions out of 39 attempts), for 288 yds and 2 TDs; while also failing to stop drives that eat up almost the entire 2nd and 3rd quarters...Manning hardly saw the field during this time. Also, if Pierre Garcon could catch, he takes a Manning pass to the house and scores, making it 17-3, and maybe dealing a major blow. Instead, he drops a sure TD, Indy has to punt. Saints go down and kick a FG cutting it to 10-6; then they get onside kick coming out of half, go down and score, and the rest is history.
2012: yes, the #4 defense. It was also the same defense that gave up 38 points to Baltimore in that playoff game, and 479 total yds of offense; not to mention the bomb by Flacco that set up the winning FG. Flacco was 18-34 for 331 yds and 3TDs; not to mention the Ravens rushed for 155 yds on 39 carries (4 ypc).
Manning having top ranked defenses that stayed top ranked in the playoffs is a myth, as well.
