In my view, this team doesn't need another skill player on the wing, they need a good-sized defender; preferably with a 3-point shot (which ain't all that easy to find).
If there's a player that proves to be appreciably better than what they've currently got in tow at the wing defensively during camp, then by all means. ... I'm all for it. There's just no one that comes to mind and the Spurs would have to be pretty damn fortunate to land a rotation player via free agency at this stage of the game.
It's very possible the Spurs will need a trade and not be able to pull one off, at least not one sufficient enough.
It is what it is. ... It's just reality, not any kind of indictment.
