I was reading the Athletic post mortem today with the argument to run it back with PG13. It's a conundrum as he's terrific and a version of this squad with a healthy Kawhi (similar to Philly words about Embiid) is still scary. Don't really see a better option.
That said, beyond the obvious question for both Philly and L.A. of what are the chances they'll be healthy for a playoff run, in the Clippers case you do get a strong sense that they don't care very much. Kawhi, PG13, and Harden are all L.A. kids. Per your thought that PG might just prefer to stay home to be with kids, I can easily imagine a team not just older by a year but also even more dis-spirited than this squad -- just going through the motions for the 9 to 5 job before heading home to a Malibu mansion (put that way, can't say I'd blame them).
