Is there really such a thing as a Trojan hangover? The facts might say so.

Teams have gone just 4-11 in games immediately following a win over a Pete Carroll-coached USC squad, suggesting that a victory against the Trojans takes a serious toll. That record doesn't include Stanford's matchup this weekend against California nor the results of Utah and Texas after their bowl wins over the Trojans, since their next games didn't occur for another nine months.

Here's the listing of the teams that have beaten Carroll's Trojans and the result of their subsequent game:
