I have had the same situations on where is the shooter is located. ,Most of the time it is after the shooter comes down, and there is lot of displacement when the defender is trying to BOX out. I just call the foul right away, while going table side I now will go talk to the coach and tell him what is happening out on the floor,only if there is any questions. By the way people it is now 4 years side my loader escapdes, and I'm still using it,
not sweating as much!!!
