What about Pollard, Hulk, Freddy, and the #17 for Magloire, and maybe a 2nd round pick, + filler if needed.
Like people have said, Magloire will not be easy to get. He's got a fair contract, and they aren't trading him for crap. This may seem like a lot at 1st but look at it from a depth standpoint.
Freddy is a bench player, Pollard is an ending contract, Hulk would NOT play next year if DD is brought back, and the 17 pick wouldn't play either.
This is like almost getting Brad Miller back, although they are different players. Having Magloire, DD (if resigned), and Foster is good depth at C.
Artest/JJ (if re-signed)
SG's and SF's are the easiest to make into solid role-players.
And for New Orleans, they're getting 3 great prospects in the deal in Hulk, Freddie, and the #17 pick, plus an ending contract. That is a good deal for both teams.
