The Rockets introduced Dwight Howard on Saturday, and while the free agent big man promised he’d keep on smiling on his way to trying to help his new team win a title, he’s also got some work to do to keep his teammates similarly engaged.

Throughout the process, there had been rumblings in Houston that even after securing Howard’s services, the Rockets may not be done tinkering with the roster.

The team was said to be working to trade Jeremy Lin and Omer Asik, not necessarily due to their skill sets not being a match to play alongside Howard, but because their contracts don’t allow for a great deal of flexibility under the league’s new collective bargaining agreement.

At the introductory press conference for Howard, however, Rockets GM Daryl Morey said that for now he’s going to keep things as is from a roster standpoint.
