This is a good post regarding the interpretation of the new PSK rule.
To quote the post: "The interpretation is that PSK applies to fouls that occur after the kick has crossed the ENZ."
This seems fairly consistent with the philosophy that K is giving up possession of the ball by kicking it. My first thought was why doesn't PSK apply at the actual beginning of the kick? For example, the kick begins as soon as the punter's or place kicker's foot strikes the ball.
But then I realized that K can still catch and/or recover a scrimmage kick in or behind the neutral zone and advance. So the philosophy behind PSK is that once the kick travels beyond the expanded neutral zone (which allows for normal line play), then K has truly given up possession of the ball.
So in summary, I would have to tip my cap to KWH for causing me to explore this issue more. Let me know if my understanding of the NF interpretation makes sense.
