Sorry,
@RonnieT24 you are wrong here. See the bolded first sentence and letters A and E below. Mathieu was guilty of both.
Here’s how the NFL defines pass interference, according to the rulebook:
It is pass interference by either team when any act by a player more than one yard beyond the line of scrimmage significantly hinders an eligible player’s opportunity to catch the ball. Pass interference can only occur when a forward pass is thrown from behind the line of scrimmage, regardless of whether the pass is legal or illegal, or whether it crosses the line.
Defensive pass interference rules apply from the time the ball is thrown until the ball is touched. See Article 2 for prohibited acts while the ball is in the air. Offensive pass interference rules apply from the time the ball is snapped until the ball is touched. See Article 2 for prohibited acts while the ball is in the air and Article 4 for prohibited acts prior to the pass.
What are players NOT allowed to do after the ball is thrown?
Via the NFL
rulebook:
- (a) Contact by a player who is not playing the ball that restricts the opponent’s opportunity to make the catch;
- (b) Playing through the back of an opponent in an attempt to make a play on the ball;
- (c) Grabbing an opponent’s arm(s) in such a manner that restricts his opportunity to catch a pass;
- (d) Extending an arm across the body of an opponent, thus restricting his ability to catch a pass, and regardless of whether the
player committing such act is playing the ball;
- (e) Cutting off the path of an opponent by making contact with him, without playing the ball;
- (f) Hooking an opponent in an attempt to get to the ball in such a manner that it causes the opponent’s body to turn prior to the
ball arriving; or
- (g) Initiating contact with an opponent by shoving or pushing off, thus creating separation.
