If the ball was a another shape, it wouldn't roll straight (an equally-weighted sphere is the only shape that can roll predictably).

The point is that a spherical ball, sufficiently inflated or filled, produces about the same distribution of forces no matter what its orientation. Which is why many sports (golf, tennis, soccer, Baseball, Basketball, billiards, Bowling) use round balls, so that bouncing, rolling, or hitting them the same way produces consistent rather than unpredictable results. Footballs and rugby balls can take unusual bounces and paths due to their oblong shapes.
