Agree in principle but the reasoning could be better worded IMHO: .... there is 0% difference between ruling a pass forward since no one had it clearly backward and ruling a player down prior to a loose ball since no one had the ball out before the player was down.
Considering consistency, when you're when you're following a runner, from outside the sideline, and you see his head jerk, during a tackle, from inside the field of play, but can't
actually see the opponent's hand and/or whether the facemask might have been involved, are you presuming and throwing a flag?
There's no requirement, or
rational expectation, that we always
actually see everything, but we are expected to rule correctly on everything that
we actually see.
