If schools are required to treat the athletes in those 2 sports as "employees," then it will open the door for people to eventually ask questions about the other sports. At some point in the future someone will ask a question that is based on Title IX especially if the endgame is for schools to treat all student-athletes as employees. Since that endgame can't be obtained right away, like with a lot of things in this world (i.e. the evolution of the Civil Rights amendments in this country and other similar laws/policies over the years), it has to be achieved in steps or phases. This just happens to be the first step in the process.
