Why would his refusal to take the shot keep him out longer? Genuine question, I didn't think Isaac would back down from a stance by scrutiny, he was all for being one of (the only?) player not to kneel during the bubble. Bradley Beal is also unvaxxed and I don't think fans would have the same aversion to him being on their team (also a devout Christian). Kyrie Irving was kept out but that was due to playing in New York with more strict guidelines than Florida would have.
I don't think it is fair to make people's aversion to him about his faith. Steph Curry is one of the most vocal Christians in the league and also one of the most universally loved. He also probably mentions God in everyone of his postgame comments. I personally don't think faith includes Fox news/Fauci scapegoating/vaccinations, which I think is the sticking point for many people. I also think Jaylen Brown is a headcase. I would prefer to not have either on my team in an ideal world, but there is a reason no one would ever hire me in basketball operations. I would suck at it.
