No he’s not made himself unavailable, he’s willing to play and practice he’s being denied because of a government mandate, he’s not holding out for a new contract and he’s not the only NBA player unvaccinated and no one else is being treated this way
That making himself unavailable. If he won’t follow the rules of the jurisdiction the team is in then he’s unavailable. I doubt he’s the only one. Irving’s just a high profile player in a city with a vax mandate. Nobody really cares about Bradley Beal or Jonathan Isaac. Irving is expensive and won’t be available for most of the season. His choice.
