Dueling crowds in the Dome

ATLANTA -- It's not No. 1 vs. No. 2 like it was each of the last two years.

Still, the energy in this place right now is off the charts.

They just played "Space Odyssey: 2001," which is the music South Carolina enters Williams-Brice Stadium to every week, and the Gamecocks' fans obviously went crazy.

The loudest cheer from the Auburn fans came when Cam Newton's picture appeared on the JumboTron and he was introduced as a starter.

There are buttons and shirts everywhere among the Auburn faithful supporting Newton, who was ruled eligible to play by the NCAA on Wednesday.

One shirt read: Yes we Cam!
