Carmelo Anthony has never won, ever. And I mean eer as in long beore the current Melo ever entered the league.
People get overfascinated by scorers. Scorers are crap if that's mostly all they do. Selfish little glory hounds, while the game is won elsewhere. The wide recievers of the NBA while the game is won in the trenches. Melo has always done just enough as a rebounder to come off as maybe a poor man's Nique type (who never won either btw), but he eats most of your shots, makes nobody better, and does nothing for you on defense. A player LIKE Tyreke on the other hand has been at the heart of numerous championship runs precisely because they do so much more than score. And you barely care who is back there with them. Let alone the big centers like Cousins. A scoring SF? Wroth less than any of that stuff. And this one costs you major assets, a huge chunk of your cap, and comes with enormous baggage and an entourage of cancerous characters. He's not our play, and he would be in the way of the development of guys who may very well be his betters.
We could use a SF of significance, but we don't need an overblown one dimensional shot muncher looking to use us as a cash grab. He can't save a team by himself, and his presence won't allow anyone else to do so. Think of guys like Wallace, Iggy, Prince -- all around vets who play defenese, fill the stat sheet, and can function as thrid weapons.
