Sure some student will land jobs after doing internships and through "connections" made during school, but not a whole lot of the best jobs. Many legal internships in law school are unpaid, and the organizations and employers (non-profits, judges, legal aid, solo practitioners, in-house legal depts., etc.) often cannot hire students after graduation due to their lack of experience or simply because the employer doesn't have the budget to hire new attorneys each year.
Sorry, but grades matter a whole lot for the best jobs: large firms, federal government positions, etc. Even the Cook County state's attorney prefers students in the top half of class.
The Chicago job market is pretty competitive...ask anyone who actually has any familiarity with it.
Any difference between Loyola / Kent / DePaul is marginal at best in placement. The are not heavy hitters by any stretch of the imagination. No one cares about marginal differences in ranking between schools ranked outside of the top 25 or so besides naive pre-laws that think that stuff actually matters.
