The team building issue started in 2019 when they went "all-in" to get KP. That deal is still killing them from having any meaningful draft assets to use. Then they traded Harrison Barnes, who could have been a very good 3rd option, for cap space and then proceeded to not do a damn thing with it. Then the Brunson mishap. They've just stacked so many bad choices on top of one another that there just isn't a good way out. An underrated one was not getting a fucking draft pick when Carlisle went to the Pacers. We just let him walk to another team without any compensation.
Then, to make things even greater, they decided to hire a mediocre coach with a mediocre track record and, shockingly, they are getting mediocre results. The roster mismanagement is not Kidd's fault, but he is a clown and this team should have a way better record than it does despite the injuries.
I think Nico is doing a decent job with the hand he was dealt. Lively is a huge win and I think OMax will be a player in a couple of years. The roster is better than it was last season, there just isn't a quick fix to this. They're going to have to keep drafting well and make decent upgrades via trade. They actually have young, tradeable players now which is a huge upgrade compared to the past few years.
The only thing that's fixable this season is the coach. That needs to happen.
