Interesting writeup, thanks
I agree that those who want to run Aldridge out of town to "fix" the offense don't make any sense. The team's offensive ceiling is much higher with him than without him.
That said, I disagree with criticizing Murray's play by judging it by "Beautiful Game" standards. That's just not fair. The BG only worked because you had the greatest teammate in NBA history (Duncan), a point guard with genius level basketball IQ (Parker), another guard with impeccable basketball instincts (Ginobili), multiple elite passing bigs (Diaw, Splitter) and elite role players who were unselfish (Green, Leonard, Mills). Other teams have tried to replicate the BG, with the Warriors getting the closest ... but even the Durant Warriors resorted to iso ball when the chips were down. Judging the 2020-21 Spurs by using "Beautiful Game" as the standard is like judging a kindergartener's finger painting by how it compares to van Gogh.
Murray's game is never going to be aesthetically-pleasing. He doesn't have a natural playmaking feel for the game; even when he makes good passes, it's rarely a result of him being able to read and react to what the defense is doing. Parker and Ginobili, for example, would often be a step or two ahead of the defense, so they could routinely make passes to teammates before they were even open just by understanding how the defense is rotating, etc. Murray is a oh-shiiii-he's-open-I-better-zip-it-in-there-before-anyone-notices type passer.
Going forward, it's safe to say "Beautiful Game" won't return no matter what the Spurs do or who is running the show. I've erased that standard from the equation. Now the Spurs are like every other team in that they need offensive weapons who draw attention and then use that attention to create space for shooters. So far, Murray is showing signs that he could be such a weapon. That's good -- and it's a step in the right direction. It's not going to be pretty ... but nothing will be pretty when judged against our memories of what was.
