I'll agree with the coach comment... not sure their team is remarkably better. For the first half they looked woefully outmatched. Then in true 2012-2013 Falcons tradition, the second half happened.
They have the potential to be better. You have to account for all the things Kaep can do, they have a pretty good defense, they have a solid run game with Gore, and they have Vernon Davis.
I'd say on any given day these two teams could go back and forth alternating wins and losses. I think the Niners best is better than the Falcons best, though. The Niners did make the Patriots look like children not that long ago.
