The high school jock is not a myth, but he’s not a reality that everyone encounters.
Things vary from school to school. If you’re a basketball star at a rural high school in Indiana, the whole town knows your name, and you’re treated like royalty. On the other hand, a basketball star at most of the New York City Catholic high schools I knew wasn’t Big Man on Campus. His friends thought it was pretty cool that he was doing so well, but he didn’t get or expect special treatment.
I’ll cite one example: Power Memorial High School (long since closed down) was a Catholic school in Manhattan run by the Irish Christian Brothers. Two of my uncles were members of that order, and used to take me and my brothers to Power games regularly. Now, Power usually had a VERY good basketball team, and such stars as Lew Alcindor/Kareem Abdul-Jabbar and Chris Mullin played there. But crowds were usually sparse at Power games. That’s life in the big city- kids who went to Power usually had other, better things to do in their spare time than go to school basketball games. So, some great athletes were playing great games in front of a few dozen people!
Hence, most of the basketball players I knew at Power were good students, probably a bit better than average. When you’re playing at a school where nobody’s paying all that much attention to a sport, jocks don’t get special breaks or much adulation.
I KNOW that, in many parts of Texas, high school football stars are treated like deities, and can coast through school, knowing they’ll never flunk or be disciplined, under any circumstances. But… when I was a teacher at a high school on Austin’s East side, I had several football and basketball players in my classes, and NONE of them was a stereotypical dumb jock. A few were EXCELLENT students, most were average, and only one flunked my class (even there, the kid in question was a nice, bright but lazy kid, rather than a dumb jock with a sense of entitlement)
That’s the difference between Austin and a small town in West Texas. There’s a lot to do here on a Friday night, so football isn’t the be all and end all of anyone’s existence. The stadiums were rarely full for this school’s football games. So, it was sort-of cool to be a football star, but nobody treated you like royalty. If you scored a big touchdown on Friday night, you got lots of high fives on Monday morning… but then everybody pretty much forgot about it.
So, it all depends on the location and culture of the school. My guess is, BOTH the people who complain about dumb jocks AND the people who say that phenomenon is overblown, are telling the truth as they experienced it.
