A runner may ward off opponents with his hands and arms but no other player on offense may use hands or arms to obstruct an opponent by grasping with hands, pushing, or encircling any part of his body during a block. Hands (open or closed) can be thrust forward to initially contact an opponent on or outside the opponent’s frame, but the blocker immediately must work to bring his hands on or inside the frame.

Note: Pass blocking: Hand(s) thrust forward that slip outside the body of the defender will be legal if blocker immediately worked to bring them back inside. Hand(s) or arm(s) that encircle a defender—i.e., hook an opponent—are to be considered illegal and officials are to call a foul for holding.

Blocker cannot use his hands or arms to push from behind, hang onto, or encircle an opponent in a manner that restricts his movement as the play develops.
Hands cannot be thrust forward above the frame to contact an opponent on the neck, face or head.

Note: The frame is defined as the part of the opponent’s body below the neck that is presented to the blocker.
A defensive player may not tackle or hold an opponent other than a runner. Otherwise, he may use his hands, arms, or body only:

(a) To defend or protect himself against an obstructing opponent.

Exception: An eligible receiver is considered to be an obstructing opponent ONLY to a point five yards beyond the line of scrimmage unless the player who receives the snap clearly demonstrates no further intention to pass the ball. Within this five-yard zone, a defensive player may chuck an eligible player in front of him. A defensive player is allowed to maintain continuous and unbroken contact within the five-yard zone until a point when the receiver is even with the defender. The defensive player cannot use his hands or arms to push from behind, hang onto, or encircle an eligible receiver in a manner that restricts movement as the play develops. Beyond this five-yard limitation, a defender may use his hands or arms ONLY to defend or protect himself against impending contact caused by a receiver. In such reaction, the defender may not contact a receiver who attempts to take a path to evade him.

(b) To push or pull opponent out of the way on line of scrimmage.

© In actual attempt to get at or tackle runner.

(d) To push or pull opponent out of the way in a legal attempt to recover a loose ball.

(e) During a legal block on an opponent who is not an eligible pass receiver.

(f) When legally blocking an eligible pass receiver above the waist.

Exception: Eligible receivers lined up within two yards of the tackle, whether on or immediately behind the line, may be blocked below the waist at or behind the line of scrimmage. NO eligible receiver may be blocked below the waist after he goes beyond the line. (Illegal cut)

Note: Once the quarterback hands off or pitches the ball to a back, or if the quarterback leaves the pocket area, the restrictions (illegal chuck, illegal cut) on the defensive team relative to the offensive receivers will end, provided the ball is not in the air.

Yeah. I mean, I can understand thinking Jerral Jones is a total tool and worthy of mockery for his “Americas Team” bullcrap. That’s perfectly fair and legitimate. He IS a tool. But hating the players and wanting them to get injured because of it is foolish idiocy and way over the top.

Same, for that matter, of anybody who says that about the 49ers or the Packers or the Patriots or even the Ravens. Not quite as sure about the Stoolers with how deliberately dirty they were STILL playing through even most of this season (although the Harrison suspension seems that it might have finally woken them up to stop being such scum-sucking rat-bastards about illegal hits), but even then it would still be rude. However, it might be deserved for them as a case of “turnabout is fair play”.
