Cockiness could certainly be a major factor in our slow start, but it's hard to know for sure.
I'm thinking it's a lot of little things that have added up (or subtracted down) to this miserable start.
As the sample size grows, so does my concern, but jacko is right, this team has too much talent to miss being highly competitive this fall.
I'm still firmly on the band wagon, but it's getting harder to stay optimistic.
