I think your advice is sound *one the attack is about to me made* as a general rule, but I like to focus my eyes primarily on where the fault is most likely to occur. In your example, there's no sense in focusing on the top of the net when the fault most likely to occur is nowhere near that. Similar to the concept of secondary transition, we have our default, and we have what we need to do based on what the play has laid out for us.

Take in the clues around you, focus on that, and adjust accordingly to what happens next.
