What I've heard through the grapevine.
Rudy was frustrated he wasnt getting the ball enough on offense. Others felt like he was being selfish to get into the All-Star game. Rudy was blaming Donovan for the defense. Most players have sided with Mitchell because he's more well-liked and Gobert's personality rubs people the wrong way.
So this is about more than the COVID19 thing. Covid just tipped it over the edge and hasnt given them time to excel on the court to mask the locker-room issue.
Rudy SHOULD be frustrated he wasn't getting the ball enough. Here are his FGAs in the last month of play:
9, 6, 7, 12, 8, 7, 5, 4, 4, 9, 8, 4, 3, 4.... How the hell does that make sense? ABSOLUTELY HE SHOULD BE GETTING MORE SHOTS. And all the ballhogs on this team need to stop blaming Rudy for the on-court problems of this team. He's literally the LAST problem of this team on the floor when it comes to selfishness and taking shots he shouldn't be taking. How about try to find the guy that finishes everything inside? How is it possible that for the last month one of the best finishers in the game has ONE game with over 10 field goal attempts and and 6 games with 5 or under? HOW?
On the other hand, I kind of understand them if they are pissed off at him about the coronavirus thing. The reports are that he's repeatedly made those types of jokes in the locker room and it doesn't matter if it was him catching it from Mitchell or the other way around. They are not mad about him giving them the virus, they are mad about him being irresponsible and putting other people in danger that didn't need to be put in danger. I'm not here to tell Mitchell or anybody else for how long they should be upset with Gobert, but of course at some point there has to be forgiveness and lets hope things get better when they get together after this and get the chance to talk about it and clean things up.
The NBA has a special place in hell for waiting until one of their players tested positive too, did they think they will just skate by and remain unaffected by it? What was the point of prolonging this and putting people in danger? They knew this was community spread. They knew big gatherings are among the biggest culprits of the spread but they had no problem continuing milking the market for as long as possible until one of their players tested positive.
