That's right, Clippers shoulder him and gave him huge contracts but until know he's not bringing anything for the franchise as he keeps resting because of his injury.
They can't force him as there's doctors recommendations and if he needs to rest then he should be resting, like you mentioned he's level of being a star is fading and it's the name that gives clippers some revenue those who still buying his collectibles but NBA wise as a franchise player there's no conversions after he's being acquired.
The Clippers have no identity anymore, that's also a problem. If you build around a boring personality like Kawhi and then he doesn't even play it's hard to form anything.
In the past the Clips had some sort of identity, even when they were the "never win Clippers". After that is was "lob city", which was the definitely the high point of the franchise with player like CP3, Blake Griffin and DeAndre Jordan. But now, who actually cares about the Clippers anymore, nobody. They got a shiny new arena, live in a shiny city but there is nothing interesting about them now!
Sad true, way back even they keep failing themselves losing both from Warriors and Spurs but they've got something that fans really wanting to support them, I was one of those who loves seeing CP3 throwing that high ball either with DeAndre or Blake and you'll be enjoying how they played in the air or how they manage to catch and dunks the ball.
It was pandemic season if I remember it right when Clippers was upset by the young Nuggets after they led 3-1 or something like that, it was anticipated that it might be a battle of LA's in the west but Nuggets bounce back and snatch that West finals slot from the Clippers, then the rest was all about Kawhi's injuries..
