As far as academic prowess in general... I mean, sure, Georgia Tech, UNC, Duke, Virginia, and Pittsburgh are all good schools, but I'm not sure how they're better (or "obvious[ly] better") than a group that includes UC-Berkeley, Stanford, UCLA, Washington, and UC-Boulder.
Well I'm just talking averages rather than the best of each. Washington State, Oregon State, the Arizona schools -- not awful or anything, but Louisville is the only ACC down that low.
A few years ago I had a huge spreadsheet of every conference and their USNWR rankings. I ought to refresh that.
