I'll be honest, most of the ideas in this thread look like fantasy basketball trades, not real NBA trades.
You have to consider what the Warriors want to do, and how the Cavs can help. The Warriors want to get rid of long contracts, most likely attaching young talent (not picks) to sweeten the deal. There is no reason to talk about Morrow, because he is on an extremely low contract (about one million next season) and then will become a free agent. Again, not the type of contract Golden State has any interest in moving and a strange target for the Cavs, who wouldn't want to take on a bad contract for one year of Morrow.
Here are the longest contracts:
Ellis at 4 more years, 11 million per.
Biedrins at 4 more years, 9 million per.
Maggette at 3 more years, averaging about 10 million escalating.
Turiaf at 2 more years, averaging a shade over 4 million escalating.
Ellis has publicly spat with ownership, teammates, and coaches. He is also a terrible fit along side Curry. When he was given a vote of confidence at the trade deadline, he was dismissive of his role with the team. He is the most likely to be moved.
Biedrins took his career this season, spread it out on the floor, and took a crap on it. I hope he was hurt, because he looked completely disinterested the entire season. He is being paid like a cusp all star, but played like Jay Guidinger. His contract will now be harder to move.
The Cavs shocked the heck out of me when it was announced that they liked adding Maggette if other deadline deals fall through. Part of me still believes this was a bluff to force Washington's hand, but who knows? I will say this for Maggette: when just about the entire Golden State roster packed it in and called it a year, he kept fighting. Every single game, he was attacking the basket, hustling for offensive rebounds, and seemed intent on scoring more points this season than he ever has before. I don't hate him as much as I used to.
Turiaf attacks every interior shot like he was shot out of a cannon. Its quite fun watching a team with no perimeter defense and a single-minded shot blocker like Ronny. The problem is that he often gets up gingerly after going balls out for the blocks. Fragility is his biggest concern. Offensively, he has absolutely no low post game but passes extremely well.
Any deals with Golden State would HAVE to involve one or more of these four players. Don't waste your time dreaming up deals for any of their young talent without figuring these guys in.
