William McAvoy

William James McAvoy (October 16, 1884 – September 17, 1956) was an American football, basketball, and baseball coach. He served as the head football coach at the University of Delaware (1908–1916, 1922–1924), Drexel University (1920–1921), and the University of Vermont (1925–1927), compiling a career college football head coaching record of 52–70–14.

A native of Hazleton, Pennsylvania, McAvoy attended Lafayette College, where he played football as a fullback and baseball as a left fielder. In the fall of 1906, he was elected captain of the 1907 Lafayette football team, but did not return to school the following year, instead going into business. In 1908, he played as a left fielder for the Rochester Bronchos of the Eastern League.
