I would drop Oakland for NE also. Carolina could be just having a bad week. Besides, GB is a great team this year, so don't let one game make you dump them. I have Carolina as my D, and I benched them for the Rams because I figured it would be a bad matchup. No suprise to me. If you pick up NE and play your matchups each week, you'll be in good shape!
