Complete garbage Commentating.
#1 Biased Comments - Obviously picking a favorite team to positively talk about all game long while occasionally giving a negative comment towards the team that is not the favorite. This includes disagreeing with all things positive happening to the unfavorite team. Then you go further to have a favorite player on the favorite team to talk about even though that player is on the bench as if the rest of the team does not matter as much.
#2 Any listener can tell that the commentators have little experience and knowledge of the game. Say things that have little impact to the game or uncertainty of the topics that lead to stuttering or an unanswered questions.
#3 Lack of excitement for the game.
In conclusion, leave sports altogether. Stop buying broadcasting just to ruin the experience.
