This is my biggest annoyance in pool commentary. After, let's say five wrong guesses, the commentator shouldn't open his/her mouth until AFTER the shot is taken.
I rolled my eyes when I read the Cornerman's interview. One of his mentioned co-commentators that he enjoyed working with was very prolific at the aforementioned annoyance. Even heard him on one stream second-guess SVB on his shot selection on multiple shots throughout the match, as if HIS way would have been a better choice. Of course, SVB without fail always made the shot and got position on the shot he chose to play.
I won't go into naming names, but there was another commentator mentioned by the Cornerman that I also prefer to not listen to because of his use of "two-dollar" words and approach that seemed to be aimed at educated/highly intellectual viewers that just made me want to puke. Like he's trying to prove to the audience how smart and knowledgeable he is.
Then there are the ones that don't really "commentate" but rather spew nonsense about anything and everything. They seem more concerned with conversing with the people in the chat room than talking about the actual match being played.
What I really like hearing in a pool stream is the sound of the balls being racked (when using a triangle), the balls clacking at the time of impact, the balls hitting the back of the pocket, some light background music, and some light commentary about what just happened after a shot. All this guesswork about shot/english/number of rails to be used, etc. drives me crazy (and that's a short drive). 8-ball is the worst to watch with the commentators tripping all over themselves about which ball to start with and then which pattern to get to the 8-ball. Geez Louise. Gimme a freakin' break!
Rant over. Carry on.
