So are we intentionally going to ignore the player designation of passer and the 2018 clarification on when the "passer" gets extra defenseless player protection? The book clearly states that a passer is no longer a passer after the pass ends or until he takes further part in the play after he throws a pass. Pretty clear IMHO when he immediately spikes from a shotgun that the pass has ended??? If NFHS wants to call a late DB hit on the player who caught the snap and then spiked the ball then I would suggest we could use some written guidance clarifying the existing language.
Written "guidance" is (thankfully) not necessary. It really, simply, depends on what the covering official actually observed. When he observes the
pass has ended (normally happens pretty quick). As Rule 2 has long clearly advised, the player who threw the pass, is no longer a passer, and any subsequent unsportsmanlike contact against that player, should be considered an USC foul.
