First i'll breakdown each teams needs from what i think.
Thunder- They need a big man who can rebound, block shots and provide some post defense, and a bit of low post scoring would be extremely helpful for them as well.
T-Wolves- Upgrade at the PG, one with some experience and been on some winning teams.
Nets- Upgrade at the SF, expiring deals and picks to help improve the team.
Now people have been saying Green has to go as he struggles to defend good PF's. But the big men proposed always have something wrong or a weakness which doesn't suit their needs. Varejao is injured, Kaman injuries, possibly doesn't provide the defense. Nene doesn't rebound well enough. Now what other big man around the league can block shots, play some defense, rebound and has nice offensive touch: Darko Milicic. Yes this would be a massive gamble, but high risk, high reward. He does have problems with consistency, probably due to his all over the place focus. If Scott Brooks could get him to be consistent and focus on the task at hand, he could be the best available for the Thunder. A frontcourt of Ibaka and Milicic is a much better rebounding, would provide good rim protection, be very good defensively, plus Milicic has nice offensive touch with an array of post moves.
Devin Harris has been on winning teams, and is probably in need of a fresh start as he has struggled in NJ as of late. He could provide some veteran leadership and be the upgrade at the PG that the Wolves need, he knows how to run a team, which is what the Wolves need. Cole Aldrich could provide some interior defense if he blossoms into the player he was drafted for.
NJ needs a upgrade at the SF for the time being, Travis Outlaw is severely overpaid and was not what the Nets needed, Jeff Green would be a much better upgrade at the position. And could be quite serviceable for the Nets.
Now i have not included picks in this, but New Jersey would obviously be asking for some to help rebuild the team. Particulary as they give up Devin Harris. I understand it would also be a massive gamble on OKC's part, but if Darko could get focused and be consistent, it would work out for OKC.
Thoughts and potential changes??
You're giving up Jeff Green, which is a very good player and Cole Aldrich who can turn out to be the starting center for this team in about 2 years... For Darko?
The TWolves are giving up a center who averaged 9-5 this season but their getting a young prospect center who can end up being better than him AND they get an all-star point guard?
Are you a TWolves fan?
No i'm not a Wolves fan. Devin Harris is a former all-star, who is probably unlikely to get there again due to injuries. It is also money saving from the point of the Nets. Helps in the offseason with any potential free agent signings they want to pursue.
Cole Aldrich is yet to show that he will become more then a solid defensive big man, not quite what the Thunder need. If you read what i said i mentioned Darko is inconsistent and doesn't focus all the time. He he has shown in a few games what he is capable of. It would be a big gamble but it could pay off. Jeff Green is not going to help the Thunder win a championship, he doesn't rebound, doesn't defend PF's well at all, doesn't hustle, not an inside post scorer.
The Thunder need to be getting something else in return. Like a draft pick or two.
"It would be a big gamble but it could pay off. Jeff Green is not going to help the Thunder win a championship..."
But Darko will lol? "Thunder" and "big gamble" probably don't belong in the same sentence either.
Darko has a better chance at getting the Thunder to being elite then what Jeff Green does. He isn't a better player, but he fills the Thunder need better then Green. He blocks shots, he can rebound, he can provide some interior defense, he has nice offensive inside touch. Green can't block shots, he doesn't rebound, he doesn't provide any interior defense whatsoever. Jeff Green is a better player, i'm not denying that. But Darko is "potentially" what the Thunder need to become Elite.
If the Thunder want a C who can block shots, rebound, and score on the block...then they should be going after Chris Kaman, not Darko.
Chris Kaman isn't the best post defender, and doesn't block many shots, aka 1.2 per game. He is a safer player to trade for, i'll admit that. But Darko averages something like 2.4 blocks per game, and has shown to be quite the defensive player when focused. And Darko "could" grow with a young good team like the Thunder and having someone put some accountability for him to focus. The rewards could be greater with Darko, But Kaman is the safer player to go for.
