It appears to be a lot closer than you are making it sound. Here is a video of the final, controversial touchdown of the game:
I do not believe there is any chance that the official actually managed to confuse the endzone line with the dashed line. The video makes it appear the receivers' foot was on the line, but the video was taken from a pretty bad angle so it is hard to tell. Regardless, with the momentum they had and the 2 timeouts, it appears Ensworth would have almost certainly scored, anyway. Fantastic game. Both teams fought incredibly hard and deserved to win.
