re: "Tough to beat a team twice"

Have you checked close game rematches? If a team's got the other's number I doubt the loser of the first wins the second. So, if in the first game the winning team wins by say 10pts or more then they probably win the 2nd game. But if its close suggesting that both teams are evenly matched then there might be some historical data to support it.

Btw, we were hoping in T-town on Nov5 that the trend of CNS never losing to the same coach twice in a row would hold up. It just goes to show you that some statistics are meaningless. It probably happened because Saban doesn't lose many games.
