Why do international basketballs have that weird stripe on them?

Question

How did the stripe originate? What's it for?

Answer 1

It's from Molten. I think it has that stripe so spectators (or anyone interested) can see how the ball spins. Maybe to see shooters' release or something like that.

Answer 2

there design for a better ball.....but it doesnt matter...if you a baller you can ball

Answer 3

nothing, im being completely serious when i say that some random fool in  croatia or something just thought of a design and thats how it was... adopted and stuff, it was probably some physics guy that knows what the h**l he is talkin about
