Shortly after ESPN NBA insider Shams Charania reported that the Grizzlies are "entertaining offers" for Ja Morant, Kelly Iko of Yahoo Sports said that the Houston Rockets aren't interested in trading for him. You can assume they're not among the "multiple teams" that Charania said are pursuing the 26-year-old.
At the end of December, insider Jake Fischer reported that the Rockets weren't "weighing changes to their team at the moment" and that they didn't "anticipate" doing so until closer to the end of January.
The front office didn't need to wait to make it known they're not interested in Morant, though.
