I wouldn't worry about their ranking. You should be concerned with job prospects. You really won't be getting Biglaw in Philly and probably not even even most of the smaller firms due to the unknowness and lack of alumni. If I were you, I'd try to get concrete info from Drexel on employment options like the DA's office or the Public Defender. How many people got jobs there (if any), what were their qualifications/grades/etc, where are students working in general, etc.
