(Original play) By letter of the law this is PSK, however by philosophy this needs to be previous spot.
Basically what the PSK rule is trying to do is say: "If the foul happens as part of the rush, make it previous spot. If the foul happens as part of the kick coverage, make it PSK."
It's hard to write that in a rulebook, which is why we get those weird scenarios that seem like PSK but aren't by letter of the law, and vice versa. By philosophy, make it what it's supposed to be.
