Yes, it's the standard package for "BigLaw." There used to be a database on Greedy Associates that showed the salary progression for each firm, but I can't seem to find it. They tend to move in lockstep with each other.
Graduates of the top 14 schools per US News and World Report rankings feed into these jobs. Some at lower ranked tier 1 schools end up in big law, but they are typically at the top of the class. I would bet that not a single student of the law school mentioned in the article ended up in with a $160k starting salary.
This was the best salary survey I could find: http://www.lawcrossing.com/article/900045279/1st-Year-Salari...
