I have noticed something in NBA games that I cannot find an answer for.
In NFL football, the winner of the coin toss gets to decide if they will kick or receive, and the loser gets to pick which end zone they defend. Clear enough.
I have followed my NBA team for 20 years. From the “TV” point of view, in home games they almost always defend the basket to the right in the first half, then switch at half.
But, in about 1-2 games per year, it is the other way (defending the left basket first). The announcers never make mention this. Since there’s no coin toss, how is the ‘direction’ of play determined? And if the teams have a choice, why isn’t it closer to 50% each way?
Is there even a reason for this? Is there some rarely talked about rule that I have never heard of?
