Lafayette, Lehigh and Rutgers competed for a Middle Three championship in several sports, including baseball, men's basketball and football.
[2] The principal newspapers covering Middle Three teams, The Morning Call of Allentown, Pennsylvania, and The Home News of New Brunswick, New Jersey, make no mention of the conference during their coverage of the 1970 or 1971 seasons.
[3] Lehigh changed its athletic teams' nickname to "Engineers" before the 1931 season; its current name, "Mountain Hawks", was adopted in 1996, long after the Middle Three folded.
After the Middle Three era ended, Lafayette and Lehigh continued to compete mainly with mid-sized colleges in the northeastern United States, eventually helping to found the Patriot League in Division I FCS in the 1980s.
In football, the Middle Three Conference continued a long tradition of Lafayette, Lehigh and Rutgers meeting on the gridiron.
