It's mind-boggling to me how these teams can be so sh1tty on the road. It's the same length of court, same height of the basket
The refs get caught up in the crowd, so you get more calls as home.
You also have to remember that the backdrop of the basket is different on the road. Home teams are used to seeing the basket on their home court more than on the road.
It probably helps when you sleep in your own bed the night before the game, too.
