Having been born into a Duck family and lived in Oregon my whole life, my impression is that, as is the case with most college football fan bases, there are good and bad Ducks fans. My family and friends who attend/have attended U of O are on the good side. They're knowledgeable about football, they don't trash other teams (unless it's Washington, but everyone has a rival, Dawgs fans don't pull any punches either), and they're realistic about the strength of the program. They get appropriately nervous for harder games, and they're attentive to the team's play in the easier games. On the other hand, there exist lots of brainless Ducks fans out there who really just don't appreciate football. Like I said, I feel like this is typical of most college football programs.
