The women’s DII teams have started to play against DI teams which can make them eligible for the NCAA DI Tournament. I could see the men’s DII teams finding a way to be eligible for the men’s NCAA DI Tournament. I wouldn’t look to much into them adding a women’s team meaning they’re adding a men’s team. Then add in the whole DII schools can’t have a DI team that has come up.

Stony Brook is a club them that has been mentioned as a possible future DI team, but no real proof that they have even looked at adding DI hockey.
