Yet the Spurs might never be able to put the right pieces around Kawhi because of the existence of Golden State and that they might not exist; it really is difficult to build a team around an SF as your best player (Lebron notwithstanding). At least if you acquire a Doncic/Bamba/Bagley/Ayton you give yourself a good shot down the road, especially if Murray pans out.
That doesn't even get into the obvious health concerns that prompt this hesitance to give him the supermax.
