Its a 9.9 scholarship sport, so it doesn't kill you. The facilities are already in place, as well, so the upfront costs are minimal.
I think we should add women's rifle like Ole Miss (7.2 scholarships) and beach volleyball (likely 8 scholarships) and men's soccer and we'll remain in line.
The expense of adding ice hockey, although it would be my personal favorite, is unreal. However, if we ever build a new arena, it should be built with the option to actually put ice down.
