I think there is a critical word missing from this sentence: you’ve specifically stated why law schools might care about undergrad name. I agree with you that undergrad name is a plausible factor in the admissions process (though not a particularly good one). It just doesn’t appear to be one they actually use. That’s why I want some data to back that up. For example, students with poor GPA/LSAT (25 percentile for the school) but who went to fantastic undergrad institutions nevertheless being admitted regularly. That would be very compelling.
