In order to get in doesn't have much to do with sports. Admissions is looking for the right person to be a second leiutenant in the Air Force. The Academy hardly does recruiting based on sports. However, athletics is an important part in getting in. You must be active and having a varsity letter in a sport sure would help. By having the coach wanting you in will help your chances I believe. What you need is a good GPA, recommended probably a 3.5 or higher however it is possible to get in with a lower GPA. You should be physically fit. You should also participate in extracurricular activities such as school clubs or outside organizations, NHS is great as well as CAP(civil air patrol). Good luck, I will be an applicant as off my next school year! Perhaps I'll see you there.
