Good question. I avoid trying to think of this issue.
If we are on an upwards trajectory and these guys are still getting playing time it's hard to see why anyone would be unhappy. They signed with this staff. If someone wants to give them huge NIL we would likely be able to match if we wanted.
Hausmann was somewhat unusual in that 1) there was a coaching change that made it easy to transfer and 2) it turned out he liked Michigan best before he arrived on campus as a freshman but didn't feel it was appropriate to renege on his commitment to Nebraska at the time (they offered him about a month before his commitment to Nebraska and kept trying to flip him until he signed)
I don't think we lose anyone like this TBH. Princewill comes from an area with lots of good teams so I suppose he might want to go home, but we showed interest in him and most of those schools didn't. It's hard to leave a D like this.
Could be an issue for any number of guys if White leaves, though.
Hopefully everyone is a fully-indoctrinated Cult of OOU guy now (lol).
