Harden played at a capacity Toyota Center for the first time since forcing his trade to Brooklyn in January. But unlike during Harden’s first pandemic-affected return, to a mostly empty building in March, the threadbare Nets were thrashed this time in a 114-104 loss. “Yeah, it’s frustrating. We got down early and we gave them too many opportunities,” Harden said. “It’s frustrating when you’re shorthanded so many guys and you’re trying to make up for it in so many games, especially on a back-to-back and playing 42 minutes [Tuesday in Dallas]. It’s frustrating. But there’s nothing you can do. It’s out of your control. You’ve just got to keep pushing.” Harden — who drew mostly cheers, mixed with scattered boos, during introductions — had 25 points, 11 rebounds and eight assists. And it was nowhere near enough.
