I agree as I think there should me more fouls because when down, you want to lengthen the game.
Although I can see a few good reasons to wait (until less than 24 sec):
- NBA players generally are pretty good with FTs....they are pros
- The free throws are easy to make up 5.....whereas if you get a stop and a 3, now you foul (maybe with 10 sec only) and down only 2, these FTs have a lot more pressure.
