I don't think it is a jump to suggest that Eric and his family are not handling his first season the way Clingan and his family did. At the very least, Hurley is preemptively presenting Clingan as a positive example for Eric to follow. Hurley seemed to pause and catch himself from saying "Eric and his family..." and just said "Eric...hopefully has that perspective...it worked out pretty well for Clingan."
It doesn't mean there is a culture problem at UConn. This is just the normal things that every team has to deal with year in and year out in the transfer portal era. Any of our presumed returnees could opt to transfer next year. Hurley has had a good track record of keeping his best players. Comments like this are just part of the process to keeping things in check. It would be nice to think that everyone is always happy and never entertains thoughts about what it might be like elsewhere, but that is not reality.
The truth is, Reibe is probably not a one and done. At another school, who knows? Hurley's message is be patient and it will work out. So I wouldn't say it is nothing, but I don't think it is something to be overly concerned about at this point. Worth keeping an eye on though.
