I have no desire to give up what is likely to be a lottery pick plus other prime assets for a declining 30 year old chucker who doesn't play defense. I'm laughing at some of these trades. Sully, Smart and the 2016 Brooklyn pick (lottery-likely) for 'Melo? That's far, far too much for this guy.
Anthony would make the Celtics better because he's a better player than Jeff Green, but ultimately he doesn't make the Cs a contender. With 'Melo, the Cs are probably a 4th, 5th or 6th seed team in the weak East. They might not even make the playoffs in the West. It's a trade into mediocrity and nothing more. Then when you add in his injury status, it may not be even that.
Nor do I think 'Melo will age all that well. He appears to be soft, thicker in the waist and his vertical lift is declining. His physical gifts are leaving him and he's not a guy like Pierce who can out-think his opposition because he's had to do it all his career (Pierce was always 'too slow" and yet he's one of the greats in Celtics history). Melo might have only a couple of good years left and then what? That's throwing good assets away in search of mediocrity. That's how the Celtics end up rebuilding again 3 years from now with nothing to show for it.
If we get Melo for a song then I have no problem with him being here. As I said, he makes the team better. But as structured, this team doesn't peak for 3 to 4 more years when Sully, Olynyk, Smart, Bradley and even guys like Zeller are in their primes. That's the future. That's when you trade for a stud who can come in and be that #1 piece. Danny will still have the firepower to do that (2018 Brooklyn pick plus a host of other young talent). To do it now is premature and to strip out some of the best assets the team has in order to become merely mediocre isn't a recipe for success.
