ATLANTA breakdown:
M Williams/Claxton for Hayes/Brown/Critt/Det 08 1st
Atlanta dumps Speedy's contract, get a defensive inside presence that also happens to be a large expiring, a young talented combo G, and a good SF. They do lose out on the potential of Marvin but I think they get better with this deal. Hayes (he is averaging almost identical stats as Marvinper minute played) should be a good backup or starter if ATL would still prefer to bring in Chill off the bench. Kwame could be the defensive anchor in the middle either off the bench or as a starter depending on matchups. Critt and Law push each other to win time on the floor.
DETROIT breakdown:
Prince/Hayes/Brezec/Murray/Dice/08 1st/Minny 2nd/Toronto 2nd for M Williams/Claxton/S Williams/Nachbar/Magloire
Pistons get a more agressive SF, a young big, end of bench C, and Speedy's contract. It hurts losing a core guy and great defender in Prince but the future looks brighter without the present taking too hard a hit. Losing the picks hurt but the roster will be stacked with youth as is. Depth at SF takes a hit but Hermann should be able to fill the vacancy. Dice is a big loss but there are a few FA bigs available if it becomes an issue but Williams/Sheed/Maxiell/Amir/Nachbar/Magloire/Samb should be able to hold down the fort if need be.
LA breakdown:
Odom/Brown/Critt for Prince/Dice/Collins/Murray
They get a good long defensive SF, a good vet backup PF, a slight downgrade at backup C(cheaper per but 1 year left), and a backup combo G(expiring). Prince (as should Die) should fit this team perfectly and at less money than Odom sans injuries to boot. It hurts to lose Critt but the team looks a bit better after this deal IMO.
NJ breakdown:
Collins/Magloire/Nachbar/S Williams for Odom/Brezec/Minny 2nd/Toronto 2nd
It hurts to lose the potential of Williams but the Nets should be in win now mode if they intend to keep the big 3. Odom, Kristic, Boone, Brezec looks like a better frontline than Nachbar, Boone, Williams, Collins, Magloire. Odom to me seems a perfect fit, he will be fine being the 3rd option behind VC and RJ, get boards, and help keep the flow on O moving smoothly.
They could try and sign a FA big to help fill the vacated roster spots. Birdman, PJ, C Webb, Dale Davis, ???
After thoughts:
I think NJ thinks the longest and Detroit just behind them. Atlanta does it the quickest (with LA just behin em) I would think as they free up some good loot (no Speedy, no big contract for Marvin) making it easier to keep Smith and Chill and a bit later, Horford and one of Critt/Law as well. They could probably resign both Brown and Hayes on the cheap if they work out good. Pretty nice looking future with options.
I'm about to be flamed from every angle, so mote it be.

EDIT - changed up draft picks
