I wouldn't put you anywhere but wide receiver. Based on your height and weight, as well as your catching ability, I believe that you will make a very good fit at wide receiver. You have the ideal size for a high school wide receiver.
My best advice for you is to work hard and perform very well in practice every day. In addition, what you need to do this autumn (and every offseason) is eat healthy, exercise by doing weight lifting, and either jogging or going for a long run every day. If you do these things, you will get faster, stronger, and into better shape, which will greatly improve your chances of becoming a successful, top notch wide receiver in high school football, who could go on to play college football in the future.
By the way, your chances of playing college football depend on your performance in football, especially during your senior year of high school. If you perform very well in football during your final year of high school, you will greatly improve your chances of getting recruited to play for a college football program in the future. ©
