The road playoff stat is pretty misleading for as much as it's been brought up. Since Flacco entered the league in 2008...
Flacco is 6-0 in road playoff games when his defense gives up 17 points or less
Other QBs are 12-0 in road playoff games when their defense gives up 17 points or less
Flacco meanwhile is 2-4 in road playoff games where the defense gives up more than 17 points. The impressive stat here is that the Ravens' defense has held opponents to 17 points or less half as often as THE ENTIRE REST OF THE NFL, not that Flacco has won those games. Literally EVERY QB has won those games, Flacco's defense just has given him more of them.
Since Flacco entered the league, his W/L in road playoff games is right on par with, or slightly below the average playoff QB when the defense is factored in. 100% when allowing 17 points or less (equal to the NFL average), and 33% when allowing 18+ points (below the NFL average). Again, the only difference is that the defense has allotted far more games in the first category than any other team for Flacco.
So I guess 13 Tds and 0 INTs is misleading to? 166 consecutive passes without a TD is misleading?
You also conveniently omitted Flacco winning 38-35 as a huge dog in Denver where his defense was awful, and the Super Bowl 34-31. 331/3/0 and 289/3/0 in those two games.
Below are two AFC QB numbers in the playoffs. I know which guy I would take. Do you?
QBR Yards Comp% TDs INT GP88 2931 56 21 8 1484 3150 60 20 17 15
I didn't "conveniently" leave anything out. I was very explicit that I was talking about the road playoff W/L record specifically in that post.
Flacco played great in those two games you mentioned, and if you want to say that he's a great QB on the merits of two great games during a 7 year career than that's your prerogative. My qualm is with people throwing around this playoff road win stat as if it's some huge point in his favor. It's not. It's literally the same thing that every other QB has done over the same span, he's just had more opportunities.
Mark Sanchez is 3-0 in road playoff games where his defense allows 17 or fewer points and followed one of those wins up with a 200/3/0 performance on the road against New England in a 28-21 win. That doesn't make him a great quarterback.
In fact, Flacco and Sanchez have identical road playoff W/L percentages in the two buckets we're talking about here.
When defense allows 17 points or less
Flacco: 6-0 (1.00)
Sanchez: 3-0 (1.00)
When defense allows 18+ points
Flacco: 2-4 (.33)
Sanchez: 1-2 (.33)
Sanchez's road playoff W/L percentages are literally identical to Flacco's. The fact that Joe Flacco and Mark Sanchez are the "best" at winning road playoff games since they entered the league is a sign of how useless a metric it is when you don't account for the defense, not a sign of how great Flacco and Sanchez are.
