Ok should be working, though it's kind of hit and miss for me in Chrome for the video to actually run.
Kinda annoying to use though, there's no good ID to use so a whole chunk of the URL has to be used.
So an NHL video would have the URL:
https://www.nhl.com/video/nhl-tonight-russia-advances/t-277774708/c-44801203
Everything after video/ (everything bolded) has to be used in the tag.
