Carmelo Anthony is indeed a bad defensive player, no question. Still, I think he gets more heat than he deserves to because Denver gets an undeserved bad reputation of being a bad defensive team, that they are not.
OTOH, although I don't like a bit his offensive game (too kobesque and based on 1vs1 moves), he's a really impressive scorer. However, and despite of considering him an elite offensive player, his off-the-court distractions and the fact that he frequently looks uncommitted in terms of hustling and defense, arise serious questions about how much of his undeniable talent will translate into wins.
But I think it would be worth the risk, in abstract. There's an unsurmountable problem when it comes to this particular trade, though: we already have Pierce to play his position. Ray Allen+Pierce>Pierce+Carmelo and it's not even that close. And Denver would never do this, anyway.
soap07,
Watch a few Nuggets games and count how many times Carmelo is the last guy to arrive back to the defensive end. It's despairing. If that's not laziness, what is it?

Btw, when has Ray Allen started to be seen as a onedimensional player who can't defend? Of course that he doesn't attack the rim so often as he used to and he's not the elite defender he was with the Bucks (but he's still good, much, much better than Anthony), but he's still an elite shooter who can do a lot of things when his shots aren't falling and provide above average defense.
