NFHS - Rule 5-1-2(a)

[HLin NC]

What isn't clear? 5-1-2a in part

After a first, second or third down, a new series of downs shall be awarded only after considering the effect of any act during the down other than nonplayer or unsportsmanlike conduct fouls by A, and any dead-ball foul by B.]

Note its "comma and any dead ball foul by B" You had 2nd down, a dead ball foul by B, which occurred first in order and thus the penalty is assessed against B first. (See 10-2-5) the new series is awarded and then A's penalty is assesesed.

Mark off 15 against B to the A20, 1st down A. Mark off half the distance against A to the A10, set the chains, 1-10 A from the A-10.

Found the casebook play I needed...

10.2.5 SITUATION A: With third and 8 on B’s 40, A1 advances to B’s 35 where he is downed. B1 piles on and, almost immediately thereafter, A spears B1. RULING: Both dead-ball fouls will be penalized in the order of their occurrence. This is not a double foul. However, since the yardage penalties offset, the proper signals will be given and the line-to-gain equipment will be set first and 10 from B’s 35 since the accepted penalty for the foul by B1 gave A a new series. However, if A2’s foul had occurred first, it would not be a new series. If A2’s spearing is judged to be flagrant, he shall be disqualified. (9-4-3i; 10-4-5b)

No chance of that happening!

Yes John, because none of us have ever DQ'd a player for a flagrant helmet contact. Get off it already.
