NFL Sunday playoff discussion thread (and poll)

We continue to have nothing going on with the baseball world today, so here's a thread to discuss today's NFL playoff games.  We have Packers/Cowboys in the early game and Steelers/Chiefs in the late game.

And I've got a poll that you can vote in, up until 3:30 today, on who you think will win these two games.  So talk about the games and cast your vote.
