I guess if we look at NBA's history in recent years, team owners would rather invest on young players. Just like in the case of Poole and Wiggins, they see the this 2 might be their future superstar and that it could bring them more championship, so it's a no brainer to offer them good contracts.
We can't read Green's mind but for sure, he either appreciate and very happy for the 2 or he just wish that the Warriors are going to offer him a good contract as well, so will see.
NBA has quite learned a lot in the past years when they saw those star players when getting old does not really play like how they were in their mid-20s and its a waste of money if they gonna extend them furthermore with hundreds of millions when they cannot really play the same or bring the team to the Finals. Some players are only good in the early years of their careers and only a few like LBJ can maintain their productivity on the court the rest are just backup players when they get old like Green and they only need fewer payments when they're not in their prime anymore.
