Pam Oliver's Forehead has had that stat up for a while. (Anyone know where there is an easily retrievable database to compare quarterbacks, without going through each QBs record, game by game, season by season?)
I was looking at Peyton Mannings record from last season:
http://www.nfl.com/player/peytonmann...gs?season=2012
I count 5 games where the other team scored 24 points or more.
Peyton's record in that situation from 2012 is 1 win, 4 losses, including the loss in the playoffs.
He did better in 2010:
http://www.nfl.com/player/peytonmann...gs?season=2010
I count 4 wins and 6 losses when the other team scored 24 points or more.
Even better in 2009:
http://www.nfl.com/player/peytonmann...gs?season=2010
3 wins and 2 losses.
2008:
3 wins, 3 losses.
2007:
2 wins, 2 losses, including the playoffs.
12 and 13, total for those years.
Of course, that is Peyton Manning, one of the best of all time. Let's look at someone a bit more ordinary.
Big Ben, for example.
2012:
http://www.nfl.com/player/benroethli...gs?season=2012
0 wins, 5 losses when the other team scored 24 points or more.
2011:
0 wins, 2 losses when the other team scored 24 points or more, including the playoffs.
2010:
1 and 1
2009:
3 and 2
2008:
1 and 2, including the playoffs.
2007:
2 and 5, including the playoffs.
7 and 17 total for those years.
So, let's just say it's not all that unusual to lose when your opponent puts up 24 points or more.
Now, of course, 2-27-1 is obviously quite a bit worse that 7-17, but you also have to consider that that is a career stat, including his rookie year, the team coming off of a 2-14 season, 2007 when he was playing with a separated shoulder, the golden years of Jimmy Raye, etc.
Matt Ryan was 3 and 3 last season.
Matt Schaub was 3 and 4 last season.
Vick was 0 and 11 last season. 0 and 7 in 2011.
