That's right, but the only way we have a competitive chance is if he plays like a QB who is at the top of his game. He should be the smartest he's ever been, the sharpest he's ever been, the most savvy he's ever been, the most accurate he's ever been.
Ben is something special and I'm grateful we have him, but I agree that you can't really say he's underrated. The reason he's generally not held in as high regard as P. Manning, Brady, Brees, or Rogers is because he isn't as good as any of them. He probably has more physical talent than any of them and that's why it's frustrating when he doesn't play up to it.
