I tried to dig deep because of this. I just want to know what players, coaches and assistant coaches think about him and I think your speculation might be true. Or it could be a bad police, good police rehearsal that they do behind the scenes and Scott Foster just loves to be the bad police.
We don't know. Here's the article from LA Times making a survey about top best and top worst officials dated 2016. Yes, he had been hated for a long time.

I think the deep reason was he never do conversations with whoever is trying to correct him. He doesn't admit his mistakes unlike other officials.

I think Lonzo will opt out of the Pelicans since his father wants the 3 of his sons to reunite at Charlotte Hornets. I'm not sure but I have a feeling it will going to happen.
Valanciunas is indeed a good addition for the Pelicans, and I myself is also excited to see these young Pelicans to mature and become a championship caliber team. I'm hoping Ingram and Zion to stay with the Pelicans until they win a championship.

Drafts and trades are still here to give the fans an excitement during the off season.

I love it when Joey Crawford is the referee of a game I’m watching. That guy takes no shit and does a great job. The players seem to like and respect him as well. He’s gotta be getting pretty old so if he is still going I imagine it won’t be for much longer, then I’ll be searching for my new favorite NBA referee.

I really do not get the Celtics trade, that looks nearly like "get Kemba out no matter what" type of trade, never understood why teams like Al Horford so much and pay him that much neither, he is not really a good center neither, dude plays with 14 points and 7 rebounds, that is not really a great deal, in this day and age you need centers who can either shoot and spread the floor, or at least grab more rebounds for the shooters to retry when they miss, needs to be a great pick and roll defender as well because that is used but needs to be master and pick and pop as well.

So long story short this wasn't a trade to get AH to the team, this was a move to send Kemba away no matter what and they got a deal from OKC, they didn't even get a good pick or anything, they weren't really looking for any profit on this trade, only thing they cared about was sending him away. Weird move.

It's just a coincidence, I think CP3 has a phobia on Scott Foster so he never wins a game when this guy is the referee.

If the NBA sees that he is not making his job fairly, they can easily fire him, unless the NBA themselves are involved.

I guess we should stop making this kind of theory, it's just senseless IMO.

They might focus on Brown and Tatum this time instead of putting more guards in their lineup.
This trade is one of the big ones early before the Draft pick. Most of the time they do it after.
The other was Valanciunas being sent to Pelicans for Steven Adams, Bledsoe, and two future first-round picks.

It's going to be a roller-coaster ride including the draft pick with so many good young players to choose from.

Yes, it could be that Tatum and Brown will be the center piece of Boston. And as early as before the playoffs starts, there is already a rumour that Kemba was already on the trading block. The story from an insider says that the Boston management is concern about Kemba's nagging knee injury. And it is now confirmed that he has been shipped out to OKC.

I'm interested to hear about Ben Simmons case though, we all know that how poorly he show himself in the playoffs and even Joel was vocal about it. Maybe it's time for the Sixers to trade him before next season. Same case with KP, he is so inconsistent as a Dallas and didn't compliment Luka well in the playoffs.

I saw a post on Facebook yesterday saying that the Sixers and the Raptors have a proposed trade.

Sixers will receive VanVleet, Anunoby and some picks.
Raptors will received Simmons.

Well, the Raptors did declined that trade and I think that its the better decision. Simmons' future is kinda unpredictable right now and its risky for the Raptors to get a player who can't even shoot threes and can't make free throws and will trade 2 of their most talented players. I think that the Raptors are in the rebuilding phase but this isn't the trade that they want to. Now the question is who will get Ben Simmons and where he will land this off-season . The Ben Simmons Saga continues .

Not aware of the Luka and KP thingy inside the Mavs, but definitely we have seen them in the playoffs and I would say that it is showing in the games wherein KP wil just pass the ball and doesn't want to shoot. But in any case, the management should step in and make this two a great player and Dallas in the contention for the playoffs next year or even land in the top 3 in the West. I know it's difficult because there are a lot of good teams. But Luka has proven himself already that he can carry the Dallas, he just needed another supporting cast and KP could fill that one up nicely.

If it's effective in the long run then KP should give way. Luka is not failing them. He looks like a ball hog but checking the stats, his assists have a good percentage.

Mark Cuban pointed out before that Luka and KP weren't on good terms outside the court. They gave time for these 2 players to somehow build good chemistry but still, it's not that good. It was the same case when Jason Terry joined the Mavericks and Dirk Nowitzki seems to don't like these guy. But looked at them, they worked together to bring a championship to Mavericks.

Will it happen to Luka and KP? The latter need to understand that Luka is the main guy on the Mavericks. He just needs to cooperate. Personally, I like him to stay.
