Based on your height and weight, as well as your wingspan and lifts, I believe that you will make a very good fit at defensive end. Considering your age, your size, especially your height, gives you the potential to become an elite high school varsity defensive end.
Remember, the best way to prove yourself is through actions, not words. In addition to lifting and eating healthy, you will need to work hard and prove yourself during practice every day.
By the way, your chances of playing college football depend on your performance in football during your junior, and especially senior, year of high school. If you perform very well in football during your final 2 years of high school, you will greatly improve your chances of getting recruited to play for a Division 1 College Football program in the future.
