Can Someone Explain What Is Going On In Carolina?

What is going on in Carolina right now? The Panthers are up 10-0 on the Packers who looked unbeatable last week against the Saint. Carolina is not the Saints. Defending Super Bowl champs do not lose to teams like the Panthers with a rookie quarterback. I know Cam Newton is playing well right now, but he will have his rookie woes. It always happens, it's just a matter of when.
