Clone fans don't need excuses for losses. We generally just say that the other team was flat out better. Last year, iowa, Utah, OU...flat out better. Mizzou and KSU? Those teams were flat out better. I don't think that I've EVER heard a hawk fan admit that the opponent was flat out better...usually it's just "pick an excuse" from their vast collection.
I'll admit I'm guilty of making some excuses. Some of them are more rational and truthful than others, while some are just rationalizations to make me feel better (*disclaimer: just because I admit that doesn't mean I'll stop doing it. It's therapeutic for me after a loss

).
USC in the Orange Bowl? Definitely better. That team could have given Miami a VERY good run for its money (Ohio State did get lucky in that game. Miami and USC were the two best teams by the end of the year.).
Pretty much any loss to OSU or Michigan falls under "they were better", IMO. It's the losses against the Northwestern's and Indiana's that are the ones that give me fits.
The big loss to Indiana in 2007: relatively equal teams, slight edge to Indiana. We just had NO answer for Kellen Lewis and James Hardy.
Northwestern: I don't usually feel like they were the better team (looking at them in terms of the season's body of work), but they're a matchup problem. Kind of like Iowa-PSU. Are we always the better team when we beat them? No, and 2008 is a PRIME example of that. We just have their number, like Northwestern has ours.
The 2005 loss in Ames: I didn't feel ISU was truly better than Iowa at the time (Granted, I was also 15 years old, and an even bigger homer then than I am now), but looking at the season as a whole, I think they definitely were. Much like Lewis/Hardy in 2007, we didn't have an answer for Meyer/Blythe, and that may have been the best defense Iowa State has had in some time. Ellis Hobbs, DeAndre Jackson, Lamarcus Hicks, Nik Moser, and Steve Paris made for one HELLUVA secondary; Berryman provided great pressure off the edge, Curvey was VERY underrated outside of Ames (I mean that in terms of both Iowa fans as well as Big 12 fans). I don't remember the linebackers outside of Bowen (but he was a sophomore that year, correct?). Plus the offense was pretty solid with Blythe/Flynn (two of my favorite Cyclones) on the outside and Hicks in the backfield. Barkema was a solid option at TE.
While every team has its close calls, and you can say a team was a couple plays from being (insert your desired record here), that ISU team should have won at least 2 more games (I'd include the TCU game, but had ISU won two more games in the season, they wouldn't have played TCU, and who knows who they would have played or how they'd have fared.).
The Outback Bowl in '06 I think we had a legitimate complaint with the officiating. It didn't necessarily cost us the game (Tate's pick 6 or the TD from Leak to Dallas Baker just before halftime had a much bigger impact), but it was a HUGE handicap. Even Florida fans were admitting that, saying that we got hosed. The call that burns me to this day was the facemask call on Clinton Solomon. They showed the replay on that, and he never came close to grabbing grill........he did get pulled to the ground by his own facemask by the defender, though:shocked: The announcers couldn't believe what they were seeing.
I won't got through every loss since November of 2002 (when I first got really into watching the Hawks every Saturday), but those are a few of the ones that stick out.
