How does participation in a sport like basketball prove that a person will succeed in business school?
It doesn’t prove that a person will succeed, but it does provide evidence of several characteristics. First, it demonstrates that the applicant is a team player and that may be important for projects both in business school and later in the business world. Second, it is evidence that the applicant has drive and ambition–aspects of motivation that, when properly harnessed, help to put intellectual energy to productive use. Third, people who have personal accomplishments are in general more interesting than those who have none.
