 By the 1921–22 season college hockey adopted the increasingly more common 6–aside format with the abandonment of the second center/rover position and the two point men being renamed as 'defensemen'.The change from point men to defensemen comes as a result of an alignment change where instead of lining up one in front of the other, the two defensive players would play beside one another.The ice surfaces that the players played on were not of a uniform size.
