Geno knows. If it gets any worse, Geno won't stay long. Cause it ain't no fun anymore!!
Actually, I think Geno has affirmed that UConn hasn't had this type of problem recently or to a significant degree. The latest comment I recall from him (from a few weeks ago) was (roughly), "As long as they [meaning the assistant coaches] bring me players like the ones we've had, I can coach for a long time. If that changes, that would be another story."
I don't think any player on the current team, or by all indications any of the incoming freshmen next year, have any feelings of "entitlement", and they expect to be coached hard. I'm sure they expect not to be verbally abused, but they can distinguish between needling, or merited criticism of their work or their effort, and genuine verbal abuse.
That has not always been the case. I remember reading that back in 1985 when Geno and CD both were first-year coaches, some of the inherited players on the team were just like the "entitled" players of today, and didn't react well to the Geno/CD coaching style. So they made sure not to recruit any more players of that stripe, and they have fairly well succeeded. But in relatively recent times, I do remember one freshman player whose scholarship was terminated because she persistently did not make the required effort, and another high-ranked recruit who was turned away apparently because either she or her parents expected a quasi-guarantee of playing time.
But almost universally, UConn has been able to avoid the problem. It helps that 11 NC's allows you to be selective. I see no reason to expect that will change in the foreseeable future. Fortunately there are still some players who don't feel entitled, and UConn will always draw from that subpopulation, even if it is ever-smaller as a percentage of the total recruiting pool.
