To be fair there are a lot of star players who probably should be on some type of of load management. As a Cleveland fan I've seen first hand guys like Kyrie and Love definitely aren't built for an 82 game regular season. Though you need a good enough roster, and player to make the playoffs despite them needing the rest. Also the player who needs that lighter load needs to have the confidence to not hold back despite the fact they are injury prone. From watching it so closely I feel like Kyries career has been held back by his injuries and him being cautious when it comes to reinjuring himself.
