Well we just played a good defense that forced our QB to throw bad passes without even having to rush more than 4. I thought it was pretty obvious to see watching the game.
Hell even Kent Sommers said:
The Cardinal offense was so bad that the Niners treated this game like it was a preseason game.
This is some pretty ridiculous
a priori reasoning: The 49ers are a good defense, so whatever the 49ers defense did was the best structural way to approach a quarterback they're unafraid of?
That must've been why teams were rushing 3 and dropping 8 all year last year against Derek Anderson, John Skelton, and Max Hall. Oh, wait. That's not what happened at all. Last year teams went mercilessly against our crappy QBs because they knew that they couldn't identify the hot route and get the ball to the open receiver.
Skelton has developed enough to this point that he can identify the hot receiver and get the ball to him with room to run. The next step is to flood the field with coverage players and see if Skelton can identify coverages. What Fazio said was that Skelton wasn't in that position yet. He's coming out the the Patriot League, for Christ's sake.
Next Skelton needs to work on diagnosing coverages, and the defenses around the league will start disguising them.
The fact remains that when teams are faced with good quarterbacks like Brady, Brees, Rodgers, and Manning, they don't blitz the QB if they're trying to win. They rush four or fewer and crowd the field with coverage to make the QB throw through tight windows. That's why New Orleans needs to run the ball now more than ever--to ensure that teams are putting seven or eight men in the box to open up throwing lanes.
I'm not comparing Skelton to those elite quarterbacks; Skelton's facing much more elementary coverages, but it's a step forward when teams realize that they can't blitz a young QB into making mistakes and instead sits back and asks the QB to beat them.
