Thats because alot of people only look at the competitive specialties, but if you wanted to match a less competitive specialty but at Yale, UCSF, Harvard...etc you still have to be extremely competitive. Also, you have to think most of the competitive stuff are surgical subspecialties: NSGY, Ortho, ENT, PRS..the exception is Derm. So looking at your example of Yale, sure they only had 3 ortho, and 2 NSGY but how many of their other specialties matched into prestigious institutions, i'd bet most of them did.
