you put too much emphasis on USNWR.
and according to your logic, since yale is the same every year and nyu is improving, in a few years nyu will be ahead of yale. that makes a whole lot of sense.
USNWR is OMNIPOTENT
actually yale is improving!
NYU isn't improving...NYU has the same overall score this year as last, yale doesn't but it has a higher margin between yale and #2 school now...
NYU didn't move up so much as CLS moved down
