Harder to play a team twice is a bit of a myth. The last time I looked, the team that won the first game was the smart play on the second game. It was close to seven of ten if I recall correctly. It's rare the second game resembles the first.
One of the things I hated about the playoff expansion was what Bama could face. Literally. We could have seen this team play Auburn in the last week of the regular season, then in the SECCG, then in the first round of the playoffs.
So now we're looking at playing UGA again in ATL. It's all on A&M to avoid that from what I've 'calculated.'
