I added this play because it got me into the rule book (and because the effort by the defensive lineman is a bit entertaining). The player in the video does nothing to break the rules. However, for discussion purposes, imagine the play takes place at midfield and a punter kicks the ball from where the holder is set up (about 5 or 6 yards behind the line of scrimmage).It is my understanding that the intent of 9-1-11-c is to prevent players from leaping/jumping over the wedge in front of the punter. However, as written (being overly technical I think), leaping over an offensive lineman would also be illegal during a punt play if the player is "trying to block a punt."
If one wanted to expand the conversation, imagine that the only change to the play is that player that "leaps" was not stationary within one yard of line of scrimmage when the ball was snapped.
