Walker: Probably the worst single game from a Spur in a long time from Lonnie, dude looks mentally broken. A lot of the blame for development belongs with him, but it's not like he's been developed well by Pop. Dude was a sounding like a space cadet talking about the world being a hologram who treated his hair like Samson, he needed some special attention.
Murray was more bad than good. He looks worse than the bubble, he doesn't even look as good in the pre-bubble games. Another case where a former point guard as an assistant coach to help him probably could not have hurt. Doubt he's getting any insight from Will Hardy or Mitch Johnson.
Lyles is on his way out of the NBA if he's not careful. He'll be getting minimums and LLEs from here on out, and that's the kind of deal he'd be on now if the Spurs hadn't been shanked by Morris and given a charity deal to Lyles afterwards like bad teams do. He just doesn't do anything that well. And unfortunately he's still better at everything than Samanic.
Poeltl was real bad too. No excuses for him.
Vassell looks like he should start right now with DeRozan at the 4. As bad as Aldridge has been, I do think some of it was predictable given his past moping if he didn't think he was getting the ball at the right time in the right place. White coming back whenever that happens will help a lot, but Vassell would help also as far as being a smart player on the court. Keldon Johnson might be stronger and better suited to bang as a starter instead, but Vassell's floor generaling defense and shooting might be better for the team.
Mills was pretty bad again. With FIBA Mills, it's feast or vomit, and it's probably going to be vomit 2 out of every 3 games or 3 out of 4.
As far as addressing things with trades this year:
The one semi-plausible trade I can think of is something involving DeRozan and salary for Blake Griffin. It kills the Spurs caproom for an extra year for sure, but I can't think of anything else that could plausibly work for any other trade partner. It makes the Spurs worse talent-wise, but the fit could have a decent result by creating more opportunities for other players at positions and roles they aren't getting enough time at now.
For the Spurs, Griffin will be a better PF than DeRozan, or at east more suited to it. He moves like busted Terry mings, but he's probably not any worse a defender than DeRozan at this point. And he shoots 3s, thought not well last year. He's a good passer for keeping the ball moving, good at feeding bigs down low, and would need a minutes limit giving more time to other players.
It's like trading bad for worse, but I can't see other trades that would help.
I don't even think Boston has enough room to be able to take Aldridge, what with his trade kicker and their hard cap.
