Hello!
1st and 10 on A-20. A88 wide receiver is beyond the NZ at snap (encroachment offense). The H flag him but doesn't kill the play. The action continues and the runner A22 goes out of bounds at the A-35. During the run, A55 (a) holds an opponent on the A-19, (b) commits a personnal foul against an opponent on the A-25.
I assume that in (a) the holding is ignored, only the offensive encroachment penalty is enforced, 1st and 15 on A-15, and in (b) the penalty for offensive encroachment is enforced and then the PF is enforced too as a dead ball foul, 1st and 12,5 on A-7,5.
What do you think?
Edit : 1st and 22,5 on A-7,5 instead of 1st and 20 on A-10
