And that's a reasonable implementation, too. The game changes year-to-year, but there's almost always some hard-and-fast "do this like this" area that can/should be reviewed.

If I were to implement replay, judgement calls would be out of the question for team-implemented review. (I'd give the head refs the option to use it for judgment calls, if they thought it necessary, and I'd guess that most head refs wouldn't. The bigger the judgement call, the more refs are in the huddle.) To review a call, it'd have to be something that could be seen and quantified from the video, and isn't covered by any automated systems or placement at the end of the match. (End-of-match placement, you can get 2-3 opinions in a matter of seconds.) Sounds like auto line violations, secret passage calls, and defense crossings for 2016; zone entry in 2014; contact around the protected zones in 2012 and 2013.
