I was thinking about Kiyoshi and Murasakibara. Two characters who are shown to be very big and also have a complicated relationship with their heights and how it influences their relationship with basket in completely different ways. Kiyoshi and Murasakibara other than sharing the fact that they're both tall, they also share the same position as center, they've also been given titles that were pretty big for boys their age, Murasakibara was kind of mystified and even been called a "monster" for how powerful he is and everyone always talked about how the entire group didn't feel like they were middle schoolers, Kiyoshi instead has always found himself not liking the title, saying that it didn't fit an high schooler, and how it makes him uncomfortable being called like that, which is pretty interesting to see how they're both similar and different at the same time.
Kiyoshi always had a complex because of his build and height, think about how Hyuuga was scared of him upon meeting up the first time, but then Kiyoshi revealed to be pretty armless, a "gentle giant" as they put it. But thanks to basket he found a place where his height isn't a problem, it makes him happy that he can use it for something that is also pretty fun for him. Which contributed to his love for basket, he can go all out, he is able to protect, both in a game sense and his team sense (the Kirisaki daichi game for example), thanks to his build and height.
Murasakibara on the other hand doesn't get that. They tell him he should play basketball because of his height, whether or not he actually wants to, his height and build scares people a lot, but, unlike Kiyoshi, that also happens in the game. We get a reveal that he does actually love basketball, but since he can't go all out, because his build could actually hurt someone if he actually put some effort into it, he ends up resenting a sport he likes, and that type of resentment builds up and he ends up lashing out on people who love basketball but are generally not as good as him, everyone can love basketball, give it their all and they don't even get to half what Murasakibara is capable of, so he tells them awful stuff that makes them quit, because he resents the fact that he can't go all out while other people can.
Which is also why Murasakibara and Kiyoshi especially end up clashing out like that, even though they're very similar, and maybe that's exactly why Murasakibara can't stand him specifically. In a general sense they should be able to understand each other, but since Kiyoshi for better or worse doesn't reach the build Murasakibara has, he still can't understand Murasakibara anyway. Kiyoshi is a big guy but he can still play to his full potential, at least he could before he got hurt, Murasakibara still doesn't get that until "Extra game"
