@skieurope I think you should actually read the article…not the title and dismiss it because it’s the huffington post. "In fact, James L. Shulman and William G. Bowen (the former president of Princeton and later the president of the Andrew G. Mellon Foundation) revealed these facts and many more in an important book, The Game of Life: College Sports and Educational Values, published almost a decade ago.
They go into great detail as to how they arrive at the 20% later in the article.
Back to the OP’s question…a little depending on the sport but overall most important would be if you are a recruited athlete.
