That's funny, exactly the same thing happened to me. I did all my growing up in the last year of grammar school and first year of high school. I was 6'2'' and played 3/4 (even at 6'2'' I was still 4th or 5th tallest 15 year old on our team). Grew only 2 more inches, so slid back to 3, then 2. Ended up playing PG off the bench. Italian style. Get in and hustle until you foul out or get ejected. Jack up some 3's just to show that once you were a "talent" and not a scrub.
