I don't know about the rest of the MAC schools, but it's hard to see the PSAC schools - which, of course, compete in D2 in all sports except wrestling - ever opting in to revenue sharing with their athletes, especially given their financial situations. All of Bloomsburg's roster spots should be safe - BU needs those tuition dollars to keep flowing.
Long term, don't be surprised if schools that don't opt in market themselves as "no cut". They won't compete with PSU, Iowa, etc., but more kids wrestling at more schools is, in my opinion, a good thing.
