True enough. But that’s now. Some years, Michigan has more. Three years ago, Michigan had 11 and Chicago had 7. Either way, placing an average of 2 (in the case of Michigan) or 3 (in the case of Chicago) graduates into Yale Law annually, out of hundreds of law school-bound graduates, isn’t exactly something to brag about. Princeton, which is smaller than Chicago, has 39 graduates enrolled at Yale Law school, which means an average of 13 annually. Brown has 22 (an average of 7 enrollments annually). Is Princeton vastly superior to Chicago? Or Brown for that matter?
Also, while Michigan is 5 times larger than Chicago, it does not have 5 times more law school applicants. Michigan is far more academically diverse than Chicago. I would estimate Michigan has 3 times more law school applicants than Chicago annually.
A more telling statistic would be the average total number of graduates enrolling in T14 Law schools annually out of the total number of law school applicants. I do not think Chicago would have a clear advantage over Michigan in this respect.
