As much as I prefer a 2 star/strong supporting cast ideology I have to admit that getting Melo is a no-brainer.
I can't think of a way to describe his ability to score that isn't either an understatement or hyperbole....but it is somewhere between those two.
Here is his shot chart via vorped.com for this season...
Mind you, this is from a guy who has little help around him--a lot of which has spent the season injured. His info from Synergy shows that he goes iso roughly 25% of the time and posts up another 20% (which is an interior iso of sorts). This means he is creating his own offense almost half the time and still producing those kinds of efficiency numbers. Assuming he would adjust being on a team with other elite players one could pretty safely assume those numbers will improve across the board. Add to that his size, athleticism, passing ability, and what I think is under-rated defense and he will be worth every penny.
Here is his Synergy Offensive chart:
I highlighted some numbers that jumped out to me. Could you imagine Melo posting up with Dwight on the weakside and guys like Harden, Parsons, and Hamilton on the wings? I can . As a coach, I wouldn't know where to begin in crafting an offense for this trio.
The depth concerns are valid and the thought of losing guys like Jones and Motie stings a little. The fact is Morey will bring in new guys that we will quickly learn to love (or not) just as he has done with the ones we are enamored with now.
Lin and Asik would have to go. I am not one who thinks the balloon payments are a big problem. Teams that are serious about getting better will see it as the cost of doing business and move on. They will most likely wind up going to separate teams. Even then, the complexity of moving enough salary out without bringing much back is a staggering task. That will require luck as much as any sort of skill.
While Lin/Asik will be missed I doubt there is any way one could argue their value supercedes what Melo would bring to the table--even after factoring in the loss of depth, talent, and salary flexibility.
I felt similarly about Dwight at first and have had to reconsider some perspectives and preconceived ideas I held. I think the same will be true for Melo. Houston, with that trio of stars, will be a nightmare match-up for any team. In a 7 game series the odds are in our favor because those three are all top 5 players at their respective positions.
