Lacky,
It depends on when the defensive player hits the receiver but both of those could be defenseless players, Illegal blind side block could be called on either of them. Or a personal foul for illegal contact to a defenseless player.
Section 33, Article 16 in the NFHS rulebook states: A defenseless player is a player who, because of his physical position and focus on concentration, is especially vulnerable to injury. A player who initiates contact against a defenseless player is responsible for making legal contact. When in question, a player is defenseless.
Examples of a defenseless player include, but are not limited to:
a.) a passer
b.) A receiver attempting to catch a pass who has not had time to clearly become a runner
c.) the intended receiver of a pass in the action during or immediately following an interception or potential interception
h.) a player who receives a blindside block with forceful contact not initiated with open hands
B, C & H all could back a call on illegal contact towards a receiver.
As far as if it is called every time, I am sure we can get better at calling those hits and also coaching our kids on how to do it correctly.
Unfortunately, INFC does not have instant replay to go back and take a penalty away like they do on TV so I think officials are more hesitant to call it.
College and pro officials have it made when it comes to this, if it looks bad just throw you flag and then we will decide if it was really a penalty in slow motion during 15 replays.
Safety of the kids should be the number one goal of both officials and coaches.
Your statement below:
To elaborate more on this.. last night I had a safety intercept a pass and return it for a TD but that was called back for a blindside block that was not led with the hands during the return.. why in the world can you not lead with your shoulder on that play when you can in a receiver that is also getting hit blindly as he is looking into the backfield..
