The only heavy ISO players are the team's stars, which should definitely be shipped out ASAP, but other than that there's other valuable pieces on the Spurs. The thing about playing with not one, but two mainly iso players is that their demand for the ball really affects teammates' performance (unless they're so good at scoring, like Harden, or so good at scoring+distribution that they offset their ball dominance). I want to see a full season of the young core without this vet dead weight before we can impart true judgment of their players - hopefully we can see that sooner rather than later.
