Why no more fros?

Back in my youth, the fashion was for black folks to wear "afros" which rose well above the level of the scalp. I liked them considerably more than some others I see today. And I do not understand why black basketball players are not wearing them. If you appear two or three inches taller than you are, it is bound to have a psychological effect upon the guy guarding you. For example, Artis Gilmore was 7-2 anyway, and did not really need any psychological assistance, but when he wore a fro, he was even more intimidating.
