In Middle School I played on the lowest level of traveling basketball. No one at that level has high school aspirations, much less professional. One of my teammates was not a good basketball player. The player was a 4 by default because he was taller than five feet. Personnel choices in Middle School are based exclusively on height. The player had a difficult time rebounding or scoring in the post, two rather important aspects of being a 4.
The coach was a competitive sort, a poorly veiled euphemism for someone who liked to scream at kids. The coach wanted us to be tough and competitive, so the coach screamed all through games because he did not know any other way to coach.
