The rankings are only useful if you look at groupings - roughly, top 10, top 25, 26-55, 56-86… that gives you an approximation of similar selectivity/similar quality colleges, although the environment and fit may be very different.
Law schools won’t distinguish between UVA and W&M for instance. They WILL distinguish between those and VCU or Randolph Macon, and between those and Virginia Wesleyan or Emory/Henry. USNWR minutiae won’t matter.
Another difference isn’t rankings, but breadth and depth of offering in her chosen major. Look at how many profs there are, for instance. Do they offer mostly gen eds or do they offer advanced seminars? Look at their biographies: what are their research interests?
