AccuScore: Flacco's performance key

AccuScore predicts that Baltimore quarterback Joe Flacco will play a determining role in whether Baltimore stands a chance against New England on Sunday.

Jenny Dell breaks it down in the video clip above:

If Flacco can throw for at least one touchdown and no more than one interception while getting an average of 4.5 yards per carry from the running game, the Ravens are a 56 percent favorite.

But if Flacco is sacked more than three times and turns the ball over two or more times, the Patriots are 77 percent favorites.
