I donno if you're being sarcastic, but what makes you say they're overrated? Just because of one game, their most recent game vs. the Chargers?
Aside from Clinton McDonald, Chris Clemons, Brandon Browner, and Walter Thurmond, they've maintained the same core on defense.
That overrated defense held the NFL's two best offenses, the Broncos and Saints, in last years' postseason to an average of 12.5 points per game.
But I agree with you on sitting them this weekend against the Broncos.
