Exactly. Refereeing in all sports involves calls that are relative to the game at that moment but also the game as a whole. An umpire established his strike zone, etc.
I am against too many rules involving contact / play disputes. Location and possession disputes are great for rules and booth review. Contact rules? I mean, I am just trying to imagine how unnessary roughness could be "reviewed" in a booth. Sounds like a nightmare.
So I am going to say no on PI reviews if there are only two choices. Those are too in the moment, and not just snapshots of location or possession.
