Which QB and Defense should I start this week?

I would say to go with Flacco and Ravens D. For Flacco, Carolina hasn't shown at all that they can do anything on defense. And for Ravens D, Brian St. Pierre was literally the 3rd string QB last year with the cardinals and he was signed THIS WEEK! theres no way he won't make a mistake, and if they do run the ball the whole time with mike goodson, you have to remember that goodson was the 3/4th string RB this year. so basically its a beat up on carolina day
