Championship Tiebreakers
The UCAA originally used a tiebreaker system to determine a single champion in the event multiple teams had identical won-lost records. This system was carried over to the Liberty League tiebreaker for the NCAA automatic bid. Ties occurred on three occasions, listed below. Such ties are no longer broken for the league championship (co-champions are declared) and the league now recognizes all the teams as champions in these three instances.
