jallenmorris, I present to you this wonderful thread compiled by river and kwam.
Rankings Down the Years103-t62015To think that in the early 2000s, Chicago GSB was ranked in the lower top 10, BELOW Haas for 3 different years on US News. This kind of shows that our view of H/S/W being the unshakable top-3 and the M7 notion will be just as transient as the historical rankings.
I foresee Yale becoming a "M10" school along with Tuck and Haas. What's hurting Haas, Tuck, and Yale is their small class sizes. Once Yale reaches the 300 mark, Haas gets a new building and also increases to 300, and Tuck maybe expanding (any rumors?), then there just may be a solid "M10" where the rankings within don't mean much.
