What is Interdisciplinary Studies Major?

Ok I should know this already, but I am transferring Colleges due to cost. I was majoring in Sport Management because I wanted to go to Law School and become a Sports Attorney. Now that I had to leave my previous institution and come back in state not many colleges in my state offer a Sport Management Degree. Would Interdisciplinary Studies be helpful. And what would be recommended for me to take since I want to be a Sport Attorney.
