I didn't "come around", I've been there all the time. But I thought Bwest brought up a good point: if "post scrimmage kick" fouls means those specific fouls with PSK enforcement, then 10-2-3 can't apply and everything offsets.
But I don't think that what the rule means. I think "post scrimmage kick fouls" include all those fouls that came after the kick, which would include those after the COP.
To muddy things up a bit: I originally came up with this question after reading through the NCAA rules. I know this isn't the NCAA forum, but it is my understanding that the PSK rules in the Fed were derived from the NCAA rules.
The NCAA rule is the following:
Offsetting Fouls
ARTICLE 4. If live-ball fouls by both teams are reported to the referee, the
fouls offset and the down is repeated (A.R. 10-1-4-I and VIII). Any player who
commits a foul that mandates disqualification must leave the game.
Exceptions:
1. When there is a change of team possession during a down, and the team
last gaining possession had not fouled before last gaining possession,
it may refuse offsetting fouls and thereby retain possession after
completion of the penalty for its foul (A.R. 10-1-4-II-VII).
2. When all Team B fouls are governed by postscrimmage kick rules,
Team B may refuse offsetting fouls and accept postscrimmage kick
enforcement.
3. Rules 8-3-4-c and 3-1-3-g-3 (during a try or extra period after Team B
possession).
With that wording it seems even MORE clear that the fouls should offset. Unfortunately, I have not been able to find an interpretation there either.
