QB playoff W-L records

The media often reports the playoff record for QBs in the NFL. We know that Peyton Manning is 3-6 in the playoffs and Tom Brady is 10-1. We know that Jake Delhomme is 5-1 with his only loss in the Super Bowl. What does this all mean? Why do QBs get so much credit or blame? To me, this is just silly and myopic. The QB is probably the most important player on most teams, but there are still 10 other guys on offense, 11 guys on defense, plus all the Special Teams players. When people see the QB sacked, they often blame the QB because he could have released the ball. But do they blame the offensive lineman or give credit to the defensive lineman or defensive scheme that got to the QB? Well, sometimes they do, but usually only right after the play. When they evaluate the QB afterwards, there is little talk about how the rest of the team played. This is not baseball. The QB is not the starting pitcher. Any analysis that begins with the QB's record is probably the start of a poor analysis.
