What is the author claim of the myth of the exploited athlete

Incomplete and unclear question. However, I infer you are referring to the article "The Myth of the Exploited Student-Athlete" by Barbara Osborne.

Explanation:

The author throughout the article analyses the claims that student-athletes are under-compensated by their institutions.

Furthermore, ln a sense the institutions "are making more money" than the students by exploiting the athletes through lower pay.
