Boston sends Tony Allen and Brian Scalabrine and $1 million
New Orleans sends Antonio Daniels
New Orleans then uses the $1 million to buy Scalabrine out of his $3.4 million contract. This then eliminates almost $4 million off their books, which is the main reason for the trade, and gets them really close to being under the luxury tax which is a huge concern for them. It also adds Allen, a defensive 2 to have behind the defensively challenged Peja Stojakovic, while adding no long term salary. With Darren Collison signed, he could be Paul's backup for the 10 minutes a game or so that CP3 needs a breather, so they don't miss Daniels that much.
Then after 30 days Boston resigns Scal to a veteran minimum contract for $1.18 million. Scal only takes a $1 million hit off his salary and Boston retains him for the season and in essence trades Tony for Antonio Daniels, a more than competent veteran back up PG.
This helps both teams while allowing Boston to corner the market on Daniels' and being able to use Marquis as a wing primarily which is where he is really needed.
