Research Overflow

Over the past week and a half of American Studies class I have been collecting sources in the form of books, articles, and websites. At first glance I thought that I had enough research to write ten junior theme papers on my subject. But once I read the sources that I gathered thoroughly I realized that each piece of research was very similar to the next and very repetitive. For example, I found the same quote in 5 different sources. All of these sources basically said the same things. So I went back and searched for more, but it was harder than I thought. Most of the sources I have been finding have been purely factual, but I am looking for something with an opposing viewpoint to the NCAA. I need some articles that have some biases and that express differing opinions. After searching for a few days I found only a few articles that I feel will really help me write my paper. I am wondering where else can I find articles to support some of the ideas that I have heard about briefly? For example,one of these articles said that the NCAA changed the rules just to make more money. I really like this point of view and want to learn more about it, I just dont know where to look.
