If you work in a large company, you can understand this comparison.
At review time, the ones who get the bad reviews are angry and usually vocal about it. Everyone knows they weren't the top performers or the most valuable to the organization. You can tell the ones who got the best reviews, the top performers, the ones who were ranked the highest and were rewarded with the bonuses and pay increases, because you don't hear much at all from them. At most you usually get a "my review was okay" or something equally bland if you get anything at all.
Silence here, to me anyway, means that UConn is very much in play, and the UConn athletic department and administration are keeping their cards very close to their vests while the process plays out. As others have said I would be more worried if they came out with a statement at this point.
On edit: I see Herbst came out with a statement. Acknowledges Syracuse and Pitt leaving and that it is a jolt, but it is not over yet, and really nothing more. It will be interesting to see how this plays out. It sounds like she wants this to be over soon to remove the distractions. We may hear something sooner rather than later. She also has ties to GaTech. That may help UConn's case with the ACC.
