When mentioning Carson Palmers' passer failings against teams like the Chiefs , 49ers, Etc etc last year, a question was brought to my attention.

Hey, what about Roethlisberger's failings against Jacksonville??

Yes, true he had a poor game. Well poor first half anyway. But comparing a QB's poor games in a PLAYOFF UNDERDOG ROLE, versus another QB playing as a FAVORITE in a Regular season game against the bottom feeders is not fair or accurate.

Case in point, here are some QB's , their passer ratings, and won / loss records when their team was a playoff underdog. How did they perform? here is your answer.

BRADY 5 GAMES TOTAL = 71% PASSER RATING RECORD 3-2

ROETH 3 GAMES TOTAL = 99% PASSER RATING RECORD 2-1

Pmann 5 GAMES TOTAL = 63% PASSER RATING RECORD 2-3

Montana 1 (since 86) = 34% passer rating RECORD 0-1

Marino 9 Games(86) = 71% Passer rating RECORD 3-6

ELWay 6 Games (86) = 61% Passer rating Record 1-4
