People get into top law schools largely based on college GPA and LSAT scores. If the legal training at top law schools is not better than at other schools, why don't top law firms recruit at less prestigious law schools, filtering for students with high GPAs and LSAT scores?
Law firms hire on the basis of prestige, primarily. T3, then T6, then T14.
The rule for law schools is that the harder the school is to get into, the less you have to work in that school, the less you will get in terms of actual legal skill, and the better job you will get when you get out.
Legal training is more of a factor at less prestigious schools. In fact, you probably get people with more legal knowledge and training at schools below the T14.
