There are provisions in Football Referee mechanics that provide for spotting the ball when there is a delay. BTDT with my time as referee. As an umpire a ball from the sideline could have been tossed the the Umpire, an official's time out could have been called.
The ref's farked it up. Don't care what transpired in the earlier part of the game. I hate the Cowboys but they got hosed.
I'm not the only one that thinks so...
