The officiating matched the play. Never seen a penalty enforced after a play was whistled dead in which no flag was thrown. (too many men on the field for NC)

Only to be enforced after a clock review that confirmed time had expired.

By using the previous plays unacknowledged penalty, they were able to give NC another chance since a game cannot end on a penalty of that type, even though no flags were thrown nor was any announcement made by the umpire declaring there was a penalty on the play until after the review for time...

Spoke with Al Graning who is a former SEC official and was on the NCAA Rules committee for a number of years. He said they f-d up big time.

Oh well.
