9:38pm: A compelling reason the Rockets, Warriors and Hawks may take on Howard without knowing whether he'll re-sign is the possibility of flipping him to the Nets, says Chris Mannix of SI.com (Twitter links). The Rockets' continued pursuit of Howard has no bearing on their offer sheet to Omer Asik, K.C. Johnson of the Chicago Tribune hears (Twitter link).
3:55pm: While the Magic appear to be putting Howard talks on the backburner for now, a source tells Ken Berger of CBSSports.com that Orlando would listen if the Nets (and presumably any other team) came forward with new proposals.
3:44pm: While Hennigan refused to share the specifics of the conversation he had with Howard today, both Alex Kennedy of HoopsWorld and Jarrod Rudolph of RealGM.com hear that the GM told Howard: "Sorry, we tried" (Twitter links). Based on Hennigan's comments and various reports, it's clear Howard won't be dealt to the Nets, at least until January 15th. The star center could still be dealt this offseason, though the Magic GM acknowledged that D12 could open the season in Orlando.
3:13pm: Speaking to the media this afternoon, Hennigan said it's "not accurate" that the Magic have suspended trade talks, adding that the team is leaving every door open. However, the Magic GM seemed to at least acknowledge that a deal with the Nets looks very unlikely. He also said he spoke to Howard earlier today, though he declined to share the specifics (all four Twitter links).
2:46pm: The Magic have informed Dwight Howard that they are suspending trade talks involving him, reports Jarrod Rudolph of RealGM.com (via Twitter). According to Rudolph, GM Rob Hennigan told Howard that the team tried to make a deal, but didn't find one that Hennigan and the front office felt met the Magic's needs (Twitter link). The club will now focus on finding its new head coach.
If the Magic are done exploring a Howard trade for the time being, it almost certainly removes the Nets from the equation. Brooklyn is said to be closing in on a new contract for Brook Lopez, which would mean the center, who is the Nets' primary trade chip, couldn't be moved until at least January 15th.
The Magic were also reportedly in talks with the Lakers, Rockets, and Hawks, and it's not clear if or when the club will re-open discussions on Howard. As Brian Schmitz of the Orlando Sentinel points out (via Twitter), despite the bad blood between Howard and the Magic, Orlando would still love to have him back for next season.
