For the 1987 and 1988 seasons, the league was known as the Eagle Pro Box Lacrosse League; from the 1989 season until the conclusion of the 1997 season, the league was known as the Major Indoor Lacrosse League. In 1998, the Major Indoor Lacrosse League changed to become the National Lacrosse League. During the entire non-NLL name era (1987-1997), a different trophy was awarded to the league champion called the North American Cup. It was a tall, skinny, sliver-colored trophy that somewhat resembled the Stanley Cup.
^In 1998, the Champion's Cup was awarded to the winner of a best-of-three series. Philadelphia won the first two games 16-12 and 17-12, respectively.
^In 2014, the Champion's Cup Finals consisted of two games. The first was hosted by the lower seed and the second by the higher seed. If neither team won both games, a 10-minute mini-game was played immediately following the conclusion of Game 2; if still tied, 10-minute sudden death overtime periods thereafter. Calgary won Game 1, 10-7. Rochester won Game 2, 16-10. Rochester won the mini-game, 3-2.
^In the first 3-game series since 1998, the Rush defeated the Rock two game to none, winning game 1 15-9 and game 2 11-10.
