I'd still bet on the Niners based on what I saw last week and their last 2 drives. Atlanta has been containing CK pretty well, but that appeared to be breaking down in the 2nd quarter.
That said, if Ryan can continue his awesome play, Atlanta will continue to put points up. I am very glad this looks like it's going to be a close one. Pats can learn a lot either way (if the Pats face 1 of these teams).
