Yes, in a heartbeat.
Carmelo is a top 15 player in the NBA, maybe top 10
Whatever Jeff Green is doing for this team now, Melo can do plus more.
And sure, Carmelo is a chucker, and I don't mind that. Scorers shoot. If Melo don't "chuck" the ball then I might as well have Gerald Wallace. But Melo is an underrated passer and a good rebounder which something that we can't say about Green.
There's so many possessions between him and Rondo, they will both have their share of the basketball and do what they want with it. But now instead of worrying about one guy on the offense, the defense worries about two.
