While the Orlando Magic are keeping all of their options open, Dwight Howard is not.

There are only four teams that Howard would sign a long-term contract with, according to a source close to the situation -- the Magic, New Jersey Nets, Dallas Mavericks or Los Angeles Lakers.

That severely limits the trade possibilities for Orlando, which has said it will not rule out trading Howard to any of the league's 29 other teams. Without a long-term commitment from Howard, no club is likely to put an enticing offer on the table.

Howard's stance essentially relegates the Magic, whose ideal scenario is to re-sign Howard, to trade talks only with the Nets, Mavericks and Lakers.

There has been speculation that the Chicago Bulls might be a possible destination for Howard because the Bulls offer a big-city environment, a superstar in Derrick Rose, and plenty of talent to send back to Orlando. But Howard's refusal to sign there ends that possibility.

While Orlando will field offers for its All-Star center, it also will take its time in an attempt to rebuild its relationship with Howard and improve the strength of its team.

New Magic CEO Alex Martins met with Howard Monday morning at Amway Center. Afterward, Howard sounded as if he he had softened his stance against staying in Orlando, as long as there are some changes.
