I think there are quite a few teams outside the ACC that can beat them. Nearly any top 10 caliber team probably could, and anyone in the top 5 would crush them. Being physical, as they are, only gets you so far, after that you need play makers, and BC relies too much on the QB to be the only play maker.
Inside the ACC, BC is on par with anyone. Like last year I think the ACC will have a few teams ranked roughly 12-25 at the end of the season. I expect BC to be one of them, with hopefully us being another.
