The information I heard a couple of years ago - unconfirmed at the time so take it as such - was that SHU was waiting on a realignment of Women's D1. The talk was of an addition of an women's D1 Atlantic conference. HC, SHU, Conn, Mercyhurst, would join that conference as their men's teams are there, RIT move up and do the same, and so on. I think that's been discarded or at least on the backburner now.
I don't intend to upset any SHU folks, and I haven't seen SHU women play since early last year so this might be dated. But it was obvious at that time that they had a huge gap between 5 or 6 players that could compete at D1 level and the rest of the players who were at best playing at a mediocre D3 level.
May not be the case now but SHU reminded me of when Quinnipiac first went D1 independent - some very good players but not enough school support and the money not there to attract a full competitive squad.
I've seen Union play this year and they're in the same situation. They are also underfunded. They have a few more D1 level players, which makes them competitive enough to grab a game or two at D1, but the drop off is still apparent.
