I really don't know anyone who played division 1 sports and marched during the summer. Actually, I never heard of any collegiate athlete who competed with the best and had such an interest in music, or majored in music for that matter. It would be really cool though, to have a both perspectives and experiences. But if camps and practice don't coincide with one another it's possible. Must be extremely dedicated and passionate about both activities since D1 athletes live and breath their respective sport, not to mention adding school work to the equation.
