Yes it is! KML is a public figure, not just an anonymous student. We should not pry into her privacy and there are Hippa laws to protect that but we pay money to watch her perform and we have a right and a concern to be informed.
maybe I'm splitting hairs here, but I think there's a difference between "our business" and "our interest". I believe, in the most literal, narrow use of the word, that KML's immediate health is not our business. We are not family, we are not a University or Team member/employee who is involved or responsible, we are not personal friends with KML.
That doesn't mean we aren't terribly interested. We are fans, dedicated, ticket-buying, television/internet subscribing, UConn gear-wearing fans. I think you hit it on the head, Forty_Four, when you say we have "a concern to be informed" We are invested in the program, and in the progress of the individual players - but, I don't know if that rises to the level that KML's health is our "business".
