Sunday night will be crazy in Seattle. The 49ers are in town, with Carroll arch-rival Jim Harbaugh on the opposite side. You'll see Carroll pacing the sidelines like he just drank 10 cups of coffee. You'll see Harbaugh's icy stare. It’s going to be intense. The Seahawks still haven't clinched a playoff spot, despite ringing up 50 points on each of the past two opponents. Beating Harbaugh would be a perfect Christmas present for Carroll. And watch the handshake between these two coaches after the game.
