摘要
A generally spherical basketball defining a center point and including a carcass having an outer surface and a cover assembly positioned over the outer surface of the carcass. The cover assembly includes at least one cover panel. The cover panel has an outer surface including a valley base surface and first and second sets of spaced-apart projections. Each of the projections of the first and second sets of spaced-apart projections include first and second outermost surfaces, respectively. The first set of projections have an average height measured in a radial direction from the center point within the range of 0.2 to 2.0 mm from the valley base surface to the first outermost surface. The second set of projections have an average height measured in a radial direction from the center point within the range of 15 to 175 μm from the valley base surface to the second outermost surface.
