You say "this team" in your subject, but I think you get at more of the root of the problem in your post. It's not about "this team" but "this environment".
The rules have changed such that it's very easy for any player to hit the ejector seat as soon as things get a little uncomfortable or as soon as they see a shiny thing somewhere else. No lost time for a transfer, no restrictions on transfer destinations, no release needed, unlimited transfers.... coupled with a massively inflated and almost entirely unregulated NIL market that's completely out of alignment with player value, driven entirely by boosters rather than any ROI from paying for a player's NIL rights.
It's very hard to build a consistent culture with upperclassmen when the environment actively encourages player movement between teams, unless you have tons of NIL cash to throw around to retain developing players which allows you to then bring in "project" players that aren't ready-made out-of-the-box.
It's hitting teams at all levels. Even mid/low-majors that might be a threat in the tournament.... you think Merrimack wouldn't have wanted to keep Derkack, or Eastern Michigan wouldn't have wanted Acuff back? These lower level programs are getting strip mined by the major conferences in exchange for castoffs. The Ivy League has been mostly unaffected... but even Wolf left for a Michigan payday while still having Ivy eligibility, which was precedent setting.
It's churn, churn, churn... unless you are able to retain your guys, which takes some combination of NIL $$$, legitimate expectation of postseason contention, and coaching cachet. Until there's some regulation (e.g., contractual obligations tied to NIL that require reimbursement if players leave before the end of the contract period), this new era is a massive shift to what it takes to be a successful coach at the collegiate level.
