The good and especially not the T1 top law schools have not lowered their evaluation/admission standards about potential students when making acceptance decisions about applicants even though there has been a significant decline in volume of LSATs taken and applicants/applications recently.
There are still plenty of qualified applicants. The highly ranked law schools still only want to offer admission to the guys and girls with academic and other merits which indicate that they will probably perform well, graduate and go on to other great things and all that. The quality of the student body at each school is paramount.
PS: Trying to make reliable predictions about the future to form any serious inferences from LSN or other currently available data entails engaging in several common flawed methods of reasoning that are routinely tested on the LSAT.
