Although the conference has had "10" in its name since 1982, it has not had 10 members since Penn State left for the second and final time in 1991. Since then, the A10 has had anywhere from 8 to 16 full members (schools that play most of their sports in the conference). From 1997 to 2006, the A10 ran a football league, but it dropped the sport when the Colonial Athletic Association began a football league.
