Conference changes and new programs Prior to the season, the Colonial League was established as a five-member, football-only league for teams in Massachusetts, New York, and Pennsylvania. The Colonial League was a forerunner of today's Patriot League and has no connection to the later Colonial Athletic Association (today's Coastal Athletic Association).
