Whether or not someone plays sports in high school has almost no relevance to college admissions. Schools will mainly look at your test scores (SAT, ACT, etc), grades, as well as what classes you took and any general extracurricular actives you may have been involved with. Colleges will not look down on you if you decide playing sports isn't for you. A lot of students initially get involved with sports teams when they go to high school but through the next four years that number will decrease as competition increases for spots on the freshman, junior-varsity, and varsity teams. Also, other opportunities in areas you may not be aware of yet will be available. There are numerous ways to be involved in school outside of athletics (school yearbook, newspaper, drama club, DECA, National Honor Society, student officers) - these are just a few of the options that were available when I was in high school 15 years ago. As you get to your junior and senior years, some students will even have jobs outside of school. Keep your grades up and you'll be good when it comes time to find a college. If you change your mind about sports you can always try one next semester or next year.
