YouTube’s Time-Based UX Problem for Live Sports

I like to play beach volleyball here in the Toronto area. I also watch beach volleyball on YouTube, which includes a lot of live streams from the AVP league in the US. It's a fun sport that I recommend to anyone looking for a new athletic competition to follow.

In most leagues and tournaments, beach volleyball games have a 3-set format, with each set finishing when a team reaches 21 points (or higher if they're not yet ahead by 2). The third set (played if needed) will go up to 15 points (again, win by 2). Some leagues/tournaments will play all three sets up to 15. It depends on the venue, tournament, etc.
