as 1L's, id be surprised if more then 3% get 1L SA's (excluding IP people, and including people with connections).
Oh, and big law is pretty much any firm you can find on NALP. At least, thats how I look at it. Now, there is big law in major markets (pays 160K+) or big law in minor markets (pays anywhere from 95K=160K). Anyway, the later is obviously easier to get, but I doubt many fordham kids are trying to go out of major markets to work (there are better schools elsewhere in the country, so I am assuming many want to work in NY or the surrounding area). Anyway, so yea. Not a good shot.
