180 degress FOR THE NEW RULE is simply incorrect, regardless of what the CFO-W folks were told.
The receiver does, and always has had, 180 degress worth of protection. For 2012, the protection varies, dependent upon the location of the opponent. If the opponent is in the area the width of the receiver's shoulders x one-yard in front on him, then no opponent may enter that area while the receiver is in position to make the catch. No judgment. If he enters, he fouls. From the side edges of this 'frontal zone,' fanning out 90 degress either side, the receiver has the previous rule to protect him. However, these 'side' zones require judgment on our part as to whether the receiver was affected. (Note: Even though the rule doesn't state that any visible affect is required, that is the philosophy most, if not all, FBS folks use). Clean catch, no flinch, no movement to avoid the opponent - no foul. Any 'flinch,' side step, short-arm - and certainly a muff - caused by an opponent entering or passing through those side zones is foul.
The CFO-W bosses may prefer that anything in the 180 arc be called, and they will probably support all such calls. It will be hard to definitively declare a KCI call in the 180 arc to be incorrect, since judgment is involved. But to declare that the new rule applies within the 180 degrees arc is simply incorrect.
