But you're not in heels, standing on a box, wearing Louboutins or barefoot when you're playing basketball. But you are in Nikes. So if you're measuring to compare everyone shouldn't you be in the basketball sneakers you play in? Or you could use the height barefoot if all sneakers were the same.
Players change sneakers. If a guy goes from a Nike to an Adidas from one season to the next, and there is a half an inch difference, does his height get adjusted?
And are these kids measured in the same shoes they play in? An inch can be the difference between a school offering you or not. It can be the difference in where a player gets drafted. So the incentive is there for kids to game the system.
At the end of the day, I think the point of heigh measurements is relative to the other players. So why not just have a uniform system for measurement?
Lastly, do you think football players should be weighed in pads? After all, they play in pads.
