I can't speak for Teeds, but I don't see Murray's performance as a counter to the push to trade him. Again, STers need to get out of their heads the idea that you should trade away bad players and keep good ones. It's dumb and leads to unrealistic trade expectations where you want value for garbage. DJM is the poster child for a guy who'd make a ton of sense on the block. He has talent and certainly can help win games in the right situation, but he didn't develop role-player skills and doesn't have the ceiling to be a star. I think this year has been way more evidence for how low the ceilings for the Spurs' prospects actually are. Walker is the only guy who's legit showing blue-chip potential at this point, and that's only if you squint.
There's also the case to be made that Murray least fits the team out of any of the White, Murray, Walker, Vassell, Johnson and even DeRozan group. Far from being a bright spot, the WAY Murray has played has done nothing to change that. The entire offense shifting to accommodate playing him and White together with any offensive player has led to a weird system that makes it hard to generate three-point looks. He's been healthier than Derrick, and that's really important, but that is more telling of Derrick's limitations than DeJounte's advantages. It's just really hard to imagine DJM giving up the ball so much that a star could actually have it while also having a more traditional playing style that generates good shots. It's true that Murray isn't the only one at fault. DeRozan and Johnson both get it in their heads way too often to try to beat their men off the dribble in order to take contested shots. But Keldon's at least young enough to change, and DMDR is better at being a ball-dominant downhill offensive engine than Murray is.
In an ideal world, something built around a healthy, durable White and two of Walker, Vassell and Johnson is a perimeter trio with potential. It might not be realistic to such an extent that the Spurs might have to look at trading White and coaching Murray to stop calling his own number. Their ceiling is lower that way, but the floor is probably a bit higher. DeJounte's improvement as an inside scorer is commendable, and it might even make sense to see if he could develop a better feel for the game while the team is a non-compe or anyway. Certainly, the benefits of him as a willing spokesperson for the team is helpful. But if the goal is to be a good team or to create an environment to develop Walker or some young perimeter guy who is a better prospect than Walker, then even giving Murray another year might not be tenable.
