I have no illusions that DL/Quin/the FO are much more knowledgeable at basketball than any of us here. This doesn't mean they will always be right and we will always be wrong(when there is disagreement with the chosen course of action).
I've been harping on about how horrible Rubio's fit with this team would be for years before we actually traded for him(when the random "lets trade for Rubio" thread would pop up), I called it out when we traded for him, I called it out during the FIBA Euro when Rubio looked like he was seeing ghost around the rim, I called it out in pre-season, when people here laughed at me when I said Exum will take his spot at some point during the season and at this point I have no doubt he would have had he not gotten injured, I keep calling it out right now. To me it was so damn obvious. Like... you need to be blind not to see the problems it presents conceptually with our roster and with our system. He's the complete polar opposite to what fits in our system offensively. And throughout all this the FO never seemed to be even slightly concerned about Rubio-Gobert fit, about 3 non-shooters on the floor together. DL called Rubio 2017 facsimile of Jason Kidd for our system FFS.
And now when it is becoming clearer and clearer that this is not working you know what they are doing? They pull Favors out first(2-3 minutes into the game)! They double down on Rubio-Gobert! Instead of leaving Favors who is better fit with Rubio(still not great) to play with Rubio longer and make Gobert play with better floor spacers they pull the combo that has somewhat worked in the absence of Gobert and they play predominantly the combo that conceptually doesn't work and more than that - with every passing game gets proven to not work not only conceptually but in practice, too.
So yeah, forgive me for not trusting them with their management of Rubio lineups.
If it were me, I'd swallow my pride and trade Rubio for free the first chance I get. The first team that can give me an expiring for Rubio gets him, I'm shipping him out and hoping to be a player on the free agency market(once we lose Favors).
