Finally, you guys: The great Harbaugh showdown of 2011 is on. This will be just like the touch football game you played with your family earlier today, only close to 70,000 people will be in the stands and it'll be on national television. Otherwise, it's very, very similar.

Tonight's game has been billed as the "first meeting between head-coaching brothers in NFL history," "an amazing thing," and "a historic thing." It's all of those things. It's also the 9-1 Niners against the 7-3 Ravens. It should be a good one. Talk with us here.
