[ We claim:] [1.] A football comprising:an ellipsoid shaped bladder having a longitudinal axis and a generally circular transverse cross section,a plurality of rubber strips secured to the bladder and extending in a longitudinal direction, each of the rubber strips having an outer surface, a pair of longitudinally extending side edges, and a longitudinally extending V-shaped groove which extends generally parallel to the side edges, anda cover surrounding the bladder and the rubber strips, the cover being formed by a plurality of cover panels which are secured to the bladder, each cover panel having outer and inner surfaces and a pair of longitudinally extending tapered edges which taper downwardly from the outer surface to the inner surface, the tapered edges of each cover panel extending downwardly into a V-shaped groove of a rubber strip and abutting tapered edges of adjacent cover panels to form V-shaped indentations in the cover.
