I think what we saw could have been a couple of things - first, the story about covid issues may be true, and second, when they got behind in game seven they just curled up in the fetal position and quit.
I'm not so worried about the covid claims - that's just bad luck and any team that has issues at that point would p[robably try to play through it. The quitting early in game seven is a lot more concerning and reflects poorly on the coaching staff and the players. Hell, I was glad to see Ayton was unhappy. Nobody should have been happy to accept the "effort" in game seven.
