Dont know if this has been said but, most announcers or commentators are good at what they do and have the knowledge to call shots before the players excute them but a lot of them have the same fault. Everyone roots for their favorite player to win a match but when a commentator does it over and over it can get out of line. I have seen some videos where certain commentators will root for balls to scratch, players to make nothing on the break or hook themselves when they favor the other player. This makes them look very unprofessional imo. Another thing that I find funny is when a commentator will say a player made a terrible shot of say something like " what were they thinking ". If they know so much why are they not down there playing themselves.
