NBA finally updated their NBA app to make sure that all highlights videos offered closed captioning. However, not all videos will have closed captioning available. Most of the videos have the CC logo embedded in the video, but the video itself might or might not have the actual captions of what the person is saying in that video. In their new app, they have a new section in the settings called Accessibility and Closed Captioning. In that section, it answers questions on where you can get help if you need better access to specific videos for closed captioning.
