I am not saying Vivek doesn't have problems, and certainly not suggesting that he is a good owner. IIRC, in a recent survey, he was voted the worst owner in NBA (might even have been all of pro sports).
My objection was to the argument that the decision about hiring Bobby or otherwise will be made/influenced by Vivek. While I expect the owner to be involved in the decision to hire a head coach, I am not aware of his meddlesome ways of recent past, if any.
This includes the incident you have described. I wasn't aware of the conflict between Vlade and Joe, so perhaps I am too generous in giving him the benefit of the doubt. While we are on this topic, I do wonder if we have too many cooks. To a limited extent, it may be beneficial as they can act as a check against the mistakes of one person, but there is always a point where it will become an issue. While the results are far from satisfactory, I don't really fault Monte's moves. Yes, he lost Bogdan for nothing, but he did make a reasonable trade, but was bushwhacked from the other end. Same for Buddy. I think the only real quibble I have is that he paid Fox max money before he had earned it (still hasn't). Overall though, I think he has done a decent job, and if he is being stymied by Joe or someone else, perhaps we need to make some changes there.
Back to Vivek, his single worst move was firing Malone. He was the first good coach we had since Rick, and we got rid of him for some crazy Jazz idea.
