I've officiated in a gym that was really short in width and in length. You could only shoot a 3 pointer at the top of the key because around free throw line extended the 3 point line stopped at the OOB line! You could not shoot a very high arching shot because it would hit the ceiling.
It was awful because you had to "watch the ball" at the top of the shot, which means less eyes on the rebounding. This was a mens league which also meant more physical play because of less room. Needless to say I didn't go back there.
