If he's truly on the block, isn't he exactly the type of player the Suns need?
I think a combination of Morris-Lopez-Warrick/Childress and a heavily protected future 1st could get it done.
We know the Rockets stockpile players. They are getting valuable rookie in Morris and a valuable big in Lopez. If nothing else, I think they take this trade because they can flip the assets further down the road for their "superstar".
The Suns would be getting rid of one of their onerous contracts (probably Warrick) and get the scorer we need. Kevin Martin equals playoffs. It's that easy.
Just to double down on the crazy, I think the Suns should sign Diaw when he gets bought out by the Bobcats. In this scenario, he provides front court depth after the trade, but he would be a boost no matter what.
