A couple of things.  So many spot on points above, including the part about a very skittish QB. He panics at the first hint of pressure.  Couple that with an O-line that's just not very good and consistently bad play calling and yes, it's a recipe for disaster.
My fear coming in was what no one was really talking about.  I certainly wasnt and didnt want to look at the stats to confirm it.  We can talk about our D all day, but FUGA is really really good.  Statistically much better than ours.  After last night, they're only giving up 10.5 points a game.  They allow 267 total yards per game and with our 2 TDs, that's 12 total given up for the year.  
Let's face it, athletic defenses have eaten our lunch all year.  We have no answer and that was the best D we have faced and will face this season.
