[CRedskinsRule]

Here is the rule as it is written.

Article 2 Prohibited Acts by both teams while the ball is in the air. Acts that are pass interference
include but are not limited to:
(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.
(g) Initiating contact with an opponent by shoving or pushing off, thus creating a separation in an attempt
to catch a pass.

on the Edelman play, I am not sure the ball is even in the air when the slot guy gains his position, so it seems like the defender has to go around him. The fact that the defenders get tangled up with him seems more like poor coverage angles, but again, I don't know the rule and application so I'm hoping someone might have better explanations.
