The Houston Rockets have been linked to a lot of guards in trade rumors since Fred VanVleet's injury. Jrue Holiday would be as good a choice as any.
Derrick White has been floated as well. To be sure, he'd make an excellent addition to this roster. If the Rockets are willing to invest substantial draft capital to upgrade their backcourt, White would be a perfect choice.
That said, the quality of the player isn't the only variable to consider. A team also has to look at trade value. White's cost on the trade market would likely be exorbitant.
