Went to a regional semifinal to watch a friend ref. Sitting high up in the stands I noticed something strange about the court.
On both ends of the court, the 3-point ark does not intersect the top of the key properly. If you were to continue the ark itself it would run along the inside of the top of the key. Even more than that, the arks were offset a little. It looked like if you measured them, the bench sides would have a slightly greater area. After the game I went to the other sides stands and sat in the same general area in them as I did during the game. Bench side still looked larger so it was not an optical elusion. On the court you really cant tell this unless you know what you are looking for.
