Alright guys... here is the infamous play. Parepat has provided most of the details correctly with an exception or two. You will see the back judge run in (not just stand there), but he never locates the ball carrier.
I am curious... do you think he gets in or not?
When you click on the link, you will find that the quality is bad but underneath the video is an option to "watch in high quality", sometimes it will let you do that and other times it won't. Either way, watch #21 get up in the endzone and the officials' handling of the situation.
I hope it is something that everyone can learn from.
