Yeah this suggests to me that not only will Harden leave, but he is not really wanted. Harden is not a Nurse-type player. I predict they will focus more on Embiid-Maxey PnR, with PJ playing the Ibaka/Gasol role as wily veteran.
Was he responsible for giving two injury prone dudes in Leonard and George $380M over 4 years? If so, this seems just like the sort of move the Wizards would make. Having lived in DC for over 2 years, I can assure you no one will be surprised.
