[just another ref]

Interesting discussion. No doubt many of us would blow the play dead and allow the player in with no penalty if we thought we were at fault for not seeing
him. But technically I don't see any provision in the rules for doing so, and that's what I think of the test as being, all about technicalities. And what about all the variables here which are unknown? B3 may have been standing in this same spot behind the free throw shooter all night, but decided at the last split second for whatever reason to step in on this one. I think technically this is false, but in real life it is very often true, and should be. Moreover, I will file it away under BAD QUESTIONS WHICH SHOULD NEVER, EVER APPEAR ON A TEST.

Thanks for the opinions.
