If we keep choking out of playoff series due to poor management, poor execution and average play from our best players while Don puts on a show, of course there should be concern that Don might leave.
Almost every great player in the history of the NBA leaves when they are extremely frustrated. I completely get that Don is extremely frustrated after Rudy gets outplayed by Jokic one postseason then overpaid Conley goes missing while Rudy gets exposed the next postseason.
I don't think Don is planning an exit, but I think he will leave if we continue to build it around Rudy. Things have to change.
