First off, the Nets have added significant salary this off-season with the additions of Johnson, Williams, and Wallace contracts account for 50 mil of their cap space. The cap is about 58 mil. They still have cap holds on their free agents @ about 8 mil or more.
Dwight Howard wants to play for the Nets, and nothing but the Nets, but I have a better chance of beating LBJ in a game of 21 than that happening anytime in the NEAR future. Unless, he is willing to play for a minimal contract yr 1 and resign for multiple years with no regard for the luxury tax.
Secondly, The Magic are not inclined to complete a trade with the Nets for the foreseeable future as their assets... suck. Nor do I foresee a team that trades away their current assets to get him from the Magic wanting Brooklyn's others. The only asset that has been included in their trade proposal that actually has value is M. Brooks, the picks would be 26th or later. Humphries is a decent prospect to some teams other than the Magic. Lopez is a big man with foot problems.
Third, why trade a top 3 player in the league to your conference, or even worse your own division? Send him west if you must send him anywhere!!
IMO if Dwight does not want to play for the Lakers (i really don't like Bynum in Orl for Dwight straight up, or taking World Peace) and is not traded this season, or is traded and goes to free agency, what will be his best options? The Nets still will have cap constraints to signing him, and still will not have ANY S&T assets so......
1. Orlando - assuming Anderson isn't over paid, will have great flexibility with Turk being bought out.
2. Atlanta - trading Johnson was a dream come true, getting D. Harris's expiring was icing on the cake
3 Brooklyn - they will have min cap space, maybe he signs for 1 yr and resigns long-term contract in 2nd yr.
3. Dallas - they have cap room, and an Dirk, not much else.
