there's definitely an element to that, which is what i think the OP is ultimately trying to get at. i'm not going to get too into it, but i have a feeling there's more to the story than just the stats posted.
look at our three home losses this year. who knows what happened in the opener against pit. the other two were against the colts and the pats, which had some of the worst weather possible. i have to imagine that comes into play too. the home lost last year was against the chiefs, who aren't too shabby. concerning the allen years before that, he was a raw young qb, and this team wasn't very good. give it a few more years, and i don' think those numbers mean as much as some want them to right now.
