- Rockets coach Stephen Silas will focus on working out his rotations during the preseason, according to Jonathan Feigen of The Houston Chronicle. “Still trying to figure out which groups play well together,” Silas said. “Tomorrow gives us a chance to do it against another team, which is huge. It’s hard when you’re evaluating both teams at the same time. But when you’re playing against a team, you can really dive into what works well offensively or defensively.”
