In terms of content, I will say that I have liked what is being offered so far and I hope ESPN continues to expand the content (both professionally and college).

FWIW I have watched a few men's and women's water polo matches a couple of times over the years. Not only during the Summer Olympics, but also the Pac-12 teams (I forget the actual conference name) and surprisingly a couple pro games (France and Hungary). I will say it is fascinating to listen to the TV announcers for each because their "discussion topics" seemed to be very different. For the pro games I had to use the caption and translation features because the broadcasts were in French and Hungarian which made it even more interesting because the translators are typically off how something should be translated into English.
