The good news for women's hockey at P4 schools is basically they need to spend an additional 22 scholarships to account for increases in football and men's hoops (WBB was already at full 15). Baseball could add another 22 and change (have been told in past BC may spend to the max but don't have confirmation)
For BC, I'd argue women's hockey is in the top two in the pecking order to increase scholarship count (with lacrosse).
Major women's sports and increase in max scholarships:
Hockey - 8
Lacrosse - 26
Softball - 13
Volleyball - 6
Soccer - 14
Field Hockey - 15
Boston College currently under rosters in lacrosse (BC only rosters 32 players of a possible 38) , softball (23 of 25), soccer (24 of 28), and field hockey (21 of 27)
Hockey has 24 of 26 this year. Emily Mara complicates it because of playing two sports, she is counted in both for this.
Essentially Boston College has 49 additional athletes in team women's sports than the previous scholarship caps before House and could be "forced" to fund 22 due to football and basketball and maybe another 22 (or part of that) from baseball. Could be offset by cuts on the mens non-revenue side (and at least part definitely will) instead of increasing scholarships on the women's side but the new fundraising plan is focused on funding scholarships.
TLDR: BC should at a minimum be able to get close to the max of 26 scholarships for women's hockey due to being forced to match scholarship adds in football/mens hoops/baseball.
