ABSTRACT:
A football having a generally prolate spheroidal shape and opposing first and second ends. The football includes a bladder, a cover and a lacing coupled to the cover. The cover is disposed over the bladder and defines, at least in part, a first set of channels extending generally longitudinally from at or near the first end of the football to at or near the second end of the football. The cover has an outer surface defining a plurality of grooves configured to facilitate grasping and throwing of the football. The depth of the groove is greater than or equal to 0.3 mm and less than or equal to 10 mm. The width and depth of the grooves is sufficiently sized to receive a portion of one or more fingertips of a user. At least one of the grooves is positioned near the first or second end of the football.
