Delay of game

[DrMooreReferee]

A is leading by 5. They have the ball at B's 35 with 4th and 10. The clock is running and A gets flagged for delay of game. There are now 35 seconds left in the 4th quarter. B's captain wants to accept the foul for delay of game for the purposes of the clock NOT starting on the ready. However, he would also like to decline the yardage penalty thinking that 5 yards back would just give K a better chance of downing the punt deep.

Can he do this?

I say he can. Fundamental X-1 says he can.

However, a friend of mine has argued this point. In his opinion, 10-1-1 and
10-1-2 illustrates that there is a difference between live ball fouls and dead ball fouls in a captains ability to decline the yardage penalty.

Again, I disagree. I think the fundamental clearly says that yardage can be declined for ANY foul.

What yall think?
