There are whole discussions on collegeconfidential and it is a known fact that where you go for undergrad DOES matter a whole lot when applying to law school. http://web.archive.org/web/200008290...e/gradeadj.htm
This is for example how UC Berkeley Law used to reformulate the GPA of applicants depending on where they went to school. As the chart shows below, if the applicant above were to go to Miami (supposing that UC Berkeley--a top 6 law school, still used this system) would have his GPA lowered and if he went to UVA, it would have his GPA increased.
If you go to Southeast Missouri State and you go want to go to Harvard Law, you would pretty much a 4.0 and a 179+. If you went to UVA, you'd need a 3.8 and a 170. Take it as you will, but there's evidence that if you do want to go to a TOP Law school, your undergrad matters and they will be more lenient with your GPA and to a certain extent, your LSAT score.
