Watching any sport on TV, or hell, TV at all is just a huge waste of time
I disagree with TV being a "waste of time" when in reference to what it can offer. Knowledge productivity is certainly not a waste. However, because most sports shows commonly deal with the crude competitiveness of gameplay, as opposed to the dynamics in which one needs in order to show their ability, I do not believe it to be all that productive. Watching a game of chess shows incredible intellect, watching a game of football almost always shows that the person is out for conflict/drama. This applies to hockey matches, aswell; people almost always say they watch it for the fights, which is absolutely pathetic.
However, I believe the majority of my bias falls into the consideration that the people who play these sports make far too much money. Someone who passes a ball around and tackles someone shouldn't be paid 10x more than someone who risks their life every day to save others.
