Please note that this post was modified by me after I realized I misunderstood the circumstances that create a PSK foul.
I understand that everybody wants to simplify PSK and clean hands. Would that you could. But, it isn't simple. There really isn't a "window" (of time) anymore for PSK fouls. Rather, it is "circumstances."
If:
-the ball is kicked legally,
-crosses the neutral zone,
-and B gains player possession of the kicked ball or is awarded team possession of the ball at the end of the down (i.e., touchback, illegal touching)
then any Basic Spot foul by B that occurs from the snap kick until the kicked ball comes into B's possession, or B is awarded possession of the ball at the end of the down, is a PSK foul. If Team A gains legal possession of the kicked ball, or is in legal possession of the ball at the end of the down, then PSK does not apply.
And, if PSK does not apply to any B foul, then "clean hands" does not apply that foul. It might apply to some other B foul. But not that foul.
Example:
4/10, 50. Team A has five players in their backfield at the snap. A80 receives the snap, take several steps forward, and legally punts the ball. B60 then blocks A50 below the waist at the 50. B90 catches the ball at the B-10, and advances to the B-20 and runs out of bounds (or the ball flies out of bounds, or becomes a touchback, or is illegally possessed by B).
B60's illegal block is a PSK foul. Thus, Team B may elect to decline Team A's illegal formation penalty, to retain possession of the ball. (This is, in effect, the "clean hands," provision, regardless of how you look at it.) Team A may then elect to accept (or decline) the penalty for Team B's blocking below the waist foul. As we have discussed on this forum before, the only time Team A would decline B's penalty would be to deny Team B the opportunity to snap the ball in an extended period, if time in the period had expired during the down. Assuming the penalty is accepted, the penalty is then enforced according to the 3-and-1 principal at Basic Spot, which is the end of the kick (B-10). Since the spot of the foul is beyond the Basic Spot, the penalty is enforced from Basic Spot (1/2 the distance in this case), B, 1/10, B-5, Snap (25).
Example:
4/10, 50. Team A has five players in their backfield at the snap. A80 receives the snap, take several steps forward, and legally punts the ball. B60 then blocks A50 below the waist at the 50. B90 catches the ball at the B-10. B90 advances to the B-20, where he fumbles. A88 recovers the ball while grounded at the B-20.
Since Team B will NOT next snap the ball, then Team B's foul can not be classified as PSK. So, the only enforcement spot available is the previous spot. Since Team A also committed a live-ball foul, the fouls offset, and the down is repeated. A, 4/10, 50, Snap (25).
Final example:
4/10, 50. Team A has five players in their backfield at the snap. A80 receives the snap, take several steps forward, and legally punts the ball. B60 then blocks A50 below the waist at the 50. B90 catches the ball at the B-10. B90 advances to the B-20, where he fumbles. A88 recovers the ball while on his feet at the B-20, and advances to the B-15, where he fumbles and B99 recovers while grounded at the B-15.
B60's block is a PSK foul. Thus, despite the fact that Team A managed to get possession of the ball during the down, Team B may elect to decline Team A's illegal formation penalty, to retain possession of the ball. (Again, this is, in effect, the "clean hands," provision, regardless of how you look at it.) Team A may then elect to accept (or decline) the penalty for Team B's illegal contact with the snapper foul. Assuming the penalty is accepted, the penalty is then enforced according to the 3-and-1 principal at Basic Spot, which is the end of the kick (B-10). Since the spot of the foul is beyond the Basic Spot, the penalty is enforced from Basic Spot (1/2 the distance in this case), B, 1/10, B-5, Snap (25).
It isn't simple. But it is very manageable, if you just understand and accept the fact that a PSK foul does, indeed, qualify for the "clean hands" provision.
