[The Ref of OZ!!!]

"Jon Bible wrote an article about making calls based upon advantage which is like Rule 11. Other officials say call the obvious and the dangerous."

I've never heard of Rule 11, and I'm not even sure where I heard the term that I use..... "Unfair Advantage", but it sure works. The obvious.... maybe.... If the obvious is 30 yards from the play, and it has no effect on the play, I still may not call a hold, unless it's done in an unsportsman like manner.... which could be interpreted as dangerous.

I generally officiate as a linesman, on a 4 man crew, covering down field passes. "Unfair Advantage" works real well with PI. Both players have a right to attempt to catch a pass thrown.... If either player takes an unfair advantage over the other, (holding, pushing, etc.), I have a PI.
