Getting in position for the planned next move will be difficult. To create enough cap room for the kind of blockbuster trade that has been proposed, the Rockets are considering making veteran forward Luis Scola an amnesty cut, likely in the next 48 hours, a person with knowledge of the move said. That would create enough cap room for the Rockets to take on the additional contracts necessary to complete a trade for Howard. Talks on Wednesday grew “serious,” and at one point seemed close to an agreement, according to a person familiar with the process, but the Magic backed off to consider their options. Rockets are open to the three-team deal in which they would receive Lakers center Andrew Bynum with Howard going to the Los Angeles Lakers, but are primarily working directly with the Magic to acquire Howard, the individual with knowledge of the talks said. Magic officials have concerns about the health of Bynum's knees, according to two NBA sources with knowledge of the team's thinking. Bynum's lengthy injury history worries the Magic more than the fact that Bynum is scheduled to become a free agent after the 2012-13 season.
