I still don't understand why sometimes they give teams the choice between taking the penalty or the play, and sometimes they simply tack penalty yardage on to the end of the play.
"We have holding on the defense, number 34. That penalty is declined. The result of the play is a first down."
And
"We have holding on the defense, number 34. That penalty will be added to the end of the run."
What are the rules governing this? And no I'm not lazy. I've tried to look this up and can't find an explanation for this.
