Why do we watch sports? Mostly because, for one reason or another, they're entertaining.
We watch because we enjoy seeing our favorite players achieve greatness. We watch because we enjoy watching our least favorite players embarrass themselves. Not to quote Jimmy Fallon in Fever Pitch, but sports make us feel like we're a part of something bigger than ourselves.
But we also watch on the off chance that we get to see a coach throw an epic temper tantrum.
When a prominent coach publicly experiences a mental break, it makes almost as many headlines as it would if LeBron registered a quadruple-double. It's hilarious. It's humiliating. It happens just rarely enough so that it's still exciting when it does.
Grown men jumping up and down and throwing stuff. It's why we watch.
