Why are some PFs as tall as Centers?

[Beelzebub]

So yeah, just like the title of this thread, I'm wondering why some PFs are as tall as Centers and why are other Centers ridiculously taller than other Centers?

Good sir, there are special characters in the game that are ridiculously tall, such as Lloyd the Center, being 215 cm tall. Big Joe can be either Center or PF, Forgot how tall he is cause I don't have a Big Joe sadly. (probably 205 or something).
