No. I was awful, a fat kid in grade school. I was worse than pathetic in neighborhood baseball games; I was given special dispensation to keep batting because of "foul tips" when everybody else was called out after one foul strike, otherwise I'd shuffle off sobbing.
In 6th/7th grade, I said, "**** this noise" and decided to start getting better in sports. Being big and strong, I was ok in football, and doing a lot of reading and stuff, understanding I'd never be a speedy shooting guard, I got to be an ok rebounding power forward in basketball and a fairly good place hitting first baseman/OF in gym class/ rec league softball. Not good enough to make the HS varsity in any of those sports; my school was a pretty big power in a lot of sports so you had to be damn good to make the team. But I was a stud in gym classes and rec leagues.
In high school, I took up skiing, tennis and floor hockey, and got reasonably ok in those sports.
For 3-4 seasons, our subdivision had one mid-30ish guy who, rumor had it, had either played college volleyball or been invited to the Olympic trials in 64 or 68 (nobody could really get the details straight); he mowed and cleared off a vacant lot and set up a regulation size grass volleyball court, so that became a thing for a couple summers, and I got fairly good.
In high school, since I wasn't playing varsity football, baseball or basketball, I
hung around the neighborhood with other non varsity athletes and terrorized the driveway basketball, and vacant-lot touch football and softball games. From being a literal pity case a few years earlier, now I was Babe Ruth blasting home runs off neighbors' aluminum siding.
I did occasionally blunder into some fairly high level pickup hoops games in high school and college. I was usually the last guy picked, but I became useful because I wouldn't try to do **** I couldn't do, and I'd stick to doing stuff I was actually credible at (boxing out, passing, setting picks).
In the course of those games, I actually did play a few times with and against ... Earvin Johnson.
