Maybe basketball needs to be divided into two leagues for over and under 6’6". Perhaps hockey should be split by bone density. Or whatever,
Maybe not split, but we should take this into account for scoring purposes. In powerlifting, your height (and thus weight) is the main determining factor in how much you can lift. We account for this by using weight classes, but that has the problem of either dividing up everyone so finely that many weight categories in local competitions only comprise of one athlete, or grouping too many people together that competition is no longer fair. There’s also the Wilk score (getting replaced last I heard due to some drama. Not sure what they use now), which calculates an overall score based on your exact weight and allows comparisons across weight classes.
So for other sports, we could have something similar to this Wilk score. In basketball for example, it could determine how much each basket is worth for each team based on the composition of the team. It wouldn’t be perfect, but it’s probably a lot better than dividing across gender lines, and would open up competition to people who enjoy the game but aren’t insanely tall.
