Since 1992 there have been five, and only five, men's athletic team sports added by schools that were in FBS or its equivalent.
Three required a massive eight-figure donation: Penn State hockey, Arizona State hockey, and Utah lacrosse.
One required dropping another men's sport: Oregon added baseball and dropped wrestling.
Two were Michigan: added soccer and lacrosse.
That's it, that's the entire list. So, if the dream is to have a new hockey team at a school that has FBS football (not just Power 5/4/2 whatever, any level of FBS football), find an eight figure donor. Otherwise, it isn't a real discussion.
Rhode Island is FCS and Binghamton is non-football, so maybe. But I'm guessing with the House settlement, opting in, Title IX upheaval, conference realignment, etc. most schools are in a "wait-and-see" mode with their entire athletic departments.
