Situation:

A1 and B1 on the perimeter A2 and B2 in the paint. A2 moves to the free throw lane to set a pick, B2 follows and becomes stationary. A1 drives around A2 on the curl screen but then wipes out B2 because he didn't see him behind A2. If you are not looking at the defence in this situation, you won't know if B2 was stationary, in legal guarding position, or if he lunged at A1 trying to stop him from scoring and would more than likely call a block. But by watching the defence you know that B2 was stationary and had legal guarding position on the floor - easy call: Player Control on A1.

Actual situation with 6 seconds left a couple years ago. Poor A1 never saw B2 and clobered him. B won by a single point.
