He said he was hurt and wouldnt play till he was 100%. That takes out the "not fulfilling his contract" narrative you keep trying to give. Isaiah Thomas was misdiagnosed and lost out on tens of millions of dollars because of it and cant even get a contract offer. The Boston Celtics traded him and will still rake in millions upon millions next season alone not to mention future years. For that reason, I'll always side with the players for looking out for themselves in the small window they have over looking out for the team. This is a business to them. Its only entertainment to you...
No not whether or not he was "too hurt to play". Its whether he was hurt at all, and whether he wanted to risk injuring himself further and risking his future contract. Demarcus Cousins got hurt and lost out on a 200+ contract. These guys have to protect themselves over the team and I'll always support that even at the detriment to my team because again, its entertainment to me, but a livelihood that can ultimately create generational wealth to them.. Maybe it was an excuse but on the otherside, maybe it wasnt...
There is an inherent injury risk every time a player steps on the court. Unless you are advocating players shutting down once they are under contract so as not to jeopardize the next contract, I don't know what the point of this is. Cousins had a freak injury that could not have been reasonably prevented. Isaiah had a known injury and was not going to get a big pay day without proving he could still play. Honestly, he needed to avoid the first injury, not the reaggravation. Has Kawhi's side proven that there was reasonable evidence that Kawhi would suffer short or long term damage by playing? If so, I don't know how they're at this point.
For contractual purposes, I think it's fair for a player to stipulate that he is to refer to his own specialist and that there should be discourse and transparency from both sides. The story out there makes it sound like the Spurs let him seek second opinion but it is unclear if he simply sought a second opinion or if he specifically looked for one that would refuse to clear him.
You are just looking at Kawhi the businessman, which is fine, but I am looking at the contractual obligations and the conflicts of interest on both sides.
