Abstract
A football having first and second ends and including a bladder, a cover and a lacing. The cover is disposed over the bladder and defines channels. The cover has an outer surface and includes a plurality of ridges. The height of the ridge is greater than or equal to 0.7 mm and less than or equal to 10 mm. The football includes an upper central region positioned between first and second upper end regions, and a lower central region positioned between first and second lower end regions. The lacing is coupled to the upper central region. The ridges extend over the upper central region, the first and second upper end regions, and the first and second lower end. The lower central region is formed without ridges. The lacing has a first length and the lower central region has a second length that is generally equal to the first length.
