I root for Billy and Sky when they play. I admire their ability on the table and their dedication to the game.
As for commentary, I prefer people that are absorbed in the game. I've seen this before too, when commentators lose focus on the match and start talking about other stuff, playing around in the chat, multi-tasking, it just makes it hard for me. Maybe this is a new age where people are used to streaming and entertaining the audience themselves, but the only entertainment I want is on the screen. And I focus really hard on the match at hand, and find it very disruptive when people's attention lapses continuously. I find it like surfing a cell phone while at an opera.
While both players had ups and downs the level of play achieved at times on both ends was extraordinary. Both players ran through difficult racks with problem balls, clusters, banks, tough shots, tricky cue ball maneuvers and dicey layouts. They did it so continuously I can see why the untrained eye could lose interest thinking it's easy. That is why commentators should be there to keep people focused on the game and on the key parts of the game, mental and physical. Sure they can add some color and mix it up a hair, but it should be a spice, not the main dish. In my opinion.
I'd like the chance to do some commentary someday. I anticipate it will happen at some point. I have no formal training and background, but I can tell you this- I would be laser focused on the match, hanging on every ball, and would be talking about the challenges on the table and how the players responded to them.
