What should I get put on my boyfriends basketball hoodie?

My boyfriend is a starter for his schools basketball team. And I need a cute idea for what I should get put on a hoodie(for myself) without seeming too obsessive. Thanks!|||Either put his name, number, or his nickname, if he has a nickname then that would be the best idea|||Why don't you just get his number put on it? Like, his last name followed by his number. That's cute :)
