LSU would count, but they've got a legitimate excuse. They lost their whole roster and several coaches. And this year's sins can be forgiven due to last year's glory.
Auburn is probably disappointing, but other than the loss to SC, I don't find anything surprising about their season.
South Carolina can be argued to be disappointing, but raise your hand if you're surprised. I'm not.
The reason there aren't too many disappointments is that there are a lot of success stories among teams that were bad last season.
Arkansas, Ole Miss and Missouri have had great years based on what they did last year or recently.
The question, which may really hurt, is how disappointing is Tennessee? I know it's disappointing here to fans and this board, but I think the ESPN predictor had them 4-6, so the final result is not going to be far off.
