Here are the highlights of the Ohio-Idaho game:
https://www.youtube.com/watch?v=GB5MBTGaZFs If you recall, Jovon Johnson was called for a 15 yard penalty after he dove in for a touchdown. Contrary to what was reported at the time, it was not his dive that earned the penalty. If you watch the highlights, at the 2:40 mark you can see the reason for the penalty. After scoring, he ran over in front of the official, and "dusted off his shoes". If he hadn't done it right in front of the official, probably no one would have noticed, but he did, and he was flagged for it.
