pigskin. Though animal bladders were once kicked around in various games of football, pigskin was never used to make a football. Nevertheless, pigskin has been a word for a football since at least 1894, when the term was used by Amos Stagg’s University of Chicago Maroons, the great football team of that era. Footballs are made of a rubber bladder covered with a cas- ing of leather. |
