Rules on illegal contact and PI before ball is thrown?
Can a defender de-cleat/Jam a receiver before the ball is thrown under 5 yards anywhere on the field?
Ex. Receiver runs a vertical route but defender knocks him down at or before 5 yards.
Ex. Receiver runs an under route but LB knocks him down under 5 yards.
Does the 5 yards matter and can defenders completely de-cleat receivers or is that targeting? Thanks!
HS does not have the NFL illegal contact foul, so there's no 5-yard limit. But, as Altor says, it's a foul to contact an eligible receiver who is no longer a potential blocker. We interpret that as saying: if the receiver is even with or beyond the defender, significant (more than just hands) contact is a foul.
So, in your first play, if the receiver is in front of the defender, that's nothing; if he's going around and getting past when the contact occurs, it's a foul. In your second play, as I'm envisioning this, the receiver is running past and in front of the LB, who initiates the contact as the receiver pulls even with him—and that's a foul.
As for "de-cleating": that's not a rules term. Big hits are sometimes legal, sometimes targeting (if the contact is above the shoulders), and sometimes illegal blindside blocks.
