Rationale:

This design is meant to target collegiate level rugby players and fans.
The font that “SBU” is based on conveys that this is a college-level sports team, as similar fonts are commonly used by colleges.
As rugby is a tough, full contact sport, the font used in “Men’s” and “RUGBY” is heavy and angular.
This is supposed to convey strength and masculinity.
Also, both fonts used have similar angled cuts on the corners of some letters which unifies the typography as a whole.
