Did anyone catch the interpretation in the POE? TE is considered inside the FBZ when the offense has normal splits.
To determine whether blocking below the waist and blocking in the back are legal, game officials must first determine whether players are in the free-blocking zone at the snap. Since offensive linemen are in the zone if any part of their body is in the zone at the snap, game officials must check the spacing between offensive linemen. As long as the line is using “normal” splits and the formation is “balanced” (i.e., the distance between the outside foot of each lineman and the inside foot of the adjacent linemen is no greater than 2 feet and an equal number of linemen are on each side of the snapper), all players, including the tight end, are deemed to be in the zone at the snap. If the splits are wider than 2 feet, the tight end is considered out of the zone and therefore cannot legally block below the waist or in the back.
