The tail of two halves

I am watching the NFC Championship game, and man it has been the tail of two halves. In the first half, it was all Arizona. They had a strong lead, and it looked like they were going to walk away with the game. Now the second half, the Eagles have taken the lead by one point. What a difference a half makes. Of course, my biggest interest is the Ravens/Steelers game, but I am somewhat routing for Arizona, so it will be interesting to see how this game continues.
