Has anyone changed their mind on this since the off-season? Our supporting cast has looked really good so far. And Carmelo would have probably squeezed Turner/Harkless out of minutes. Both of those guys play good defense, and Carmelo is not known for that. He may have demanded his shots as well, which I don't think would fit in too well with this team. The real key to this team is defense, because the offense is already good enough.
With Harkless struggling on offense, I can only imagine Melo taking those shots. But Mo maybe plays better D and is better for the long game.
