I just want to know. Is our goal to be good or to be a championship team? If it's to be a championship team, can you imagine Melo as the #1 option leading a championship team? I mean, Melo is a good player, but look at the history of the NBA. Actually, just look at the past 20 champions.
Kobe, Jordan, Shaq, Duncan, LeBron, Dirk, Hakeem, etc. Melo is nowhere near as good as any of them. I won't go as far as to say it's impossible to win with Melo as the #1 option since there will always be those "random" champions, but I find it really, really hard to imagine any scenario that has Melo leading a championship team. It's just... I just can't process that.
Then, there's another situation. Let's say we sign Melo, who eventually becomes our #2 option. I'm guessing that some people see this as one of our ideal situations, but I don't see that as an ideal situation either. For a #2, you want a player like Pau, Pippen, KG, etc. Lets take a look at 2010 KG. Current Melo is better than 2010 KG as the #1 option. Melo can create his shot any time he wants. He can score in almost any situation, even if it's not always the most efficient shot, but as a #2 player, I'd say KG is infinitely better because his abilities shine while Melo's talents are limited. KG doesn't need the ball to be effective. He can bring bigs out of the paint because he can space the floor as a big. He's always setting great (illegal) screens, and he's a great passer. I don't mean a great passer in the sense that he creates shot for others (he can do that too), but he simply doesn't stop the ball. Occasionally, he can also make plays with the ball. He plays great defense. And, despite his douchebaggery ways, he's also a leader. Melo provides none of that. Seriously, his only positive attribute is scoring the ball, and if that's not happening, he's not impacting the team positively.
I just can't see Melo as the #1 or #2 option on a championship team. He can lead some really good ones but probably not a champion.
