1. Unfortunately, Draymond Green opted out on his final contract with the Warriors, and now he is an unrestricted free agent. I guess that would be the end of the Warriors dynasty unless the Warriors will give other offer to him, but it seems like he wants to be with another team, and wants a higher salary this year.
2. They really need it, and we saw that they really need it when we saw how the Lakers just bullied them inside the paint. I still remember the times where the Lakers got McGee, David West, Speights, David Lee, Bogut, Pachulia and other bigs. I mean they're gone in the NBA already except for McGee, but it's pretty obvious that the Warriors are better if they have big players in their team. They badly need one.
3. They only have at most 2 years to win a title again. What the team needs right now are big players who can defend the paint. Green already opted out on his contract, so they need another elite defender to cover what Green left with the team.
Well, we can not say for sure if he still wanted to be in the Warriors, and based on his Podcast talking with coach Steve Kerr I think that the GSW will still want his servitude, and like I said he is helping the Warriors make it to the finals so I think the Warriors will not let him go that easily,
For me, they Badly needed 2 big players and it is a waste giving up James Wiseman but they badly needed already honed big players and maybe James Wiseman in the future he surely needs to improve himself, but as you have said JaVale McGee can also be a great addition even though he doesn't have any deep shooting his inside scoring and defensive power can provide the Warriors with great paint offense and defense,
For sure Draymond Green will not leave the Warriors but if he did getting some big players is a must for the Warriors
Well the Beal trade won't happen for obvious reasons.

Dame said he would stay in Portland, doesn't really want to leave, but he is leaving it up to the front office if they want to ship him.
Also, the Warriors just said they want to keep Poole, but we all know that might mean nothing if the right trade is getting offered. If they can get a good big man like Bam or DeAndre A. he would be gone fast. Though, Miami and Phoenix have no use for Poole. The Suns are stacked with shooters and Miami would rather get Lillard of course.
Lauri Markannen would be a nice addition, but there is no reason for Utah to trade their only allstar player.
Well if those trades I think is not possible then focusing on getting big men is a must, but it is a crucial addition that it will revolve around Stephen Curry, in addition to what I think Karl-Anthony Towns if he decided to be traded, or Deandre Ayton if the Phoenix Suns wouldn't want him to be in their team anymore, he surely is a great addition to the Warriors for sure,
I don't think they will let go of Draymond Green because they already established a strong bond with him, and they will have a hard time again if they replace him with some other player that will not be going to listen and do what they said. we all know other players are hard to tame. At least Green knows his limit when he does trash-talk and does some nasty things inside and outside the court. But if they have someone who is more capable of playing and has the skills to replace him, he will be replaced this year and might not get his chance back to play with the GSW.
I totally agree with that. Draymond Green is the heart of the Warriors' defense. The players move well because Draymond knows how to facilitate the ball and improve the team's defense. I can't imagine what would happen to the Warriors without him. If we look at the statistics from last season when Draymond Green was absent, I believe they had a negative impact, and they improved significantly when Draymond returned.
Draymond leaving is the price the Warriors would have to pay for choosing Poole over Draymond in terms of salary contract.
Well I also think that Draymond Green is a key figure for the Warrior's Success and I truly agree that he is the heart of the Warrior's Defense if he was not around the Defense will surely crumble, even making play will be very difficult without him, so just like you two I really can't imagine a Warriors team without Draymond Green,
