I'll admit that I have never seen Carmelo Anthony as a "superstar". He is a good offensive player but he is not good on defense (dare I say borderline apathetic at times) and is a bit of a ball hog and usually ends up costing his team games. You don't have to be stellar on defense to qualify as a Top 10 type player but I think you have to be at least average... Melo is not an average defender.
I'm not a fan of LeBron James but I do see him as a "superstar" talent. In the situation shown in the picture in this thread LeBron, Kobe, Wade, Dirk and other Top guys would pass the ball to either of the open guys knowing that he had no shot.
I honestly see him as a Top 30 talent, Top 20 max. Call me whatever you want but that's just the way I see it.
