You bring up a good point. There have been a whole slew of postings here lately where perfectly reasonable officials, for no explainable reason, want to solve whatever quandary they have gotten themselves into...by going to the arrow.
If I were king of basketball, I think I'd take the arrow away until these folks learned how to properly solve the 99% of situations that resume using POI or some means other than the arrow. Then maybe, and only maybe, I'd give it back.
