BusinessWeek rankings are not very well respected by most people.

Although it isn't a guarantee the people there are bankers, a significant portion of them are, and the consensus is that the rankings are BS. If you really look at iit from an objective point of view, their rankings really make no sense at all - forget that you're so gung-ho about notre dame, and take a real look.
BYU over NYU Stern and one behind Michigan Ross? A good 5 rankings ahead of Haas? Please.
ND at #3? Cornell jumping 10 ranks in one year? Emory at #5 ahead of michigan, MIT, NYU Stern, UBerk Haas?
Uh huh.
edit: i realize this is for business as a whole, which includes accounting, etc. but using these rankings for ibanking or management consulting is unreliable. USNews is much better
