Sure, lining up against Seattle/Arizona is a recipe for plug-and-play QB success.
Ask the following:

[vs. SEA]
1. Phillip Rivers, 55% completion percentage, 2 picks, 80 QB Rating (SD Loss)
2. Jay Cutler, 44% completion percentage, 0 TD's, 69 QB Rating (CHI Loss)

[vs. ARI]
1. Drew Brees, more INT's than TD's (NO Loss)
2. Kyle Orton, under 50% completion percentage, 0 TD's 3 picks (DEN Loss)

Don't give Cassel any credit. Forget his season statistics while you're at it.
Higher SEASON QB Rating than:
Both Mannings, Brees, Roethlisberger, Ryan, Flacco, Orton, Schaub and Garrard.
Still not good enough. Brilliant...
