I thought about this earlier today, thanks for posting. I think there's a good chance Phil puts Melo on the trading block, and goes young.
I would not want to take Melo because, a. I think the price tag would be too high, and b. we would be throwing our eggs into the "win it all" now basket, and frankly, Melo alone is not going to get us to that promised land. He is only going to decline as a player, and I am not interested in paying him max dollars during the twilight of his career.
