They ARE marketing to people who have never played their game before. Why is that surprising? They are trying to increase NCAA Basketball's fanbase to the level of NCAA Football or beyond.
The whole point of marketing is to get people who usually won't buy your product to actually buy it. OS consists of a lot of hardcore college basketball fans who will buy a "new and improved" NCAA Basketball game no matter what. We are not the target audience, and improved dynasty sim stats is not a mass appeal feature for the general public.
