Whoa! I thought Vince Carter might be on the move, but I wasn’t expecting this.

The New Jersey Nets have agreed to a trade in principle with the Magic that will send Vince Carter and Ryan Anderson to Orlando for Rafer Alston, Tony Battie and Courtney Lee, two league sources told ESPN.com.

As for the Nets, the move is a cost-cutting measure. Both Alston and Battie are in the last year of their contracts, and trading for them would shave $16.5 million off New Jersey’s roster in the summer of 2010 and put the Nets well below the salary cap.

Now this is a trade that helps both teams, unlike the Suns’ Shaq giveaway and the Bucks’ donation of Richard Jefferson to the Spurs’ championship fund. Not only do the Nets get loads of salary cap relief — Carter has three years and $52 million remaining on his contract — they get a nice prospect to replace him in Courtney Lee, who averaged better than 11 points per game and 43% 3PT shooting in February and March. The Nets project to go into the summer of 2010 with almost $30 million in cap space.

For the Magic, Carter adds a boost of athleticism to lineup of spot up shooters. But how will this affect the team’s ability to re-sign Hedo Turkoglu? If they can get him to re-up, they’d have a lineup of Jameer Nelson, Carter, Turkoglu, Rashard Lewis and Dwight Howard that looks deadly on paper. I think they’re planning on retaining him, but the Magic are looking at a pretty hefty payroll over the next few years with Carter on the roster.
