Turns out there are a lot more videos on the TRRA Youtube channel.  Some training videos on particular topics, some short clips of one call, and some match videos with Texas refs.  Check it out.

The TRRA does good webinars pretty frequently and posts them on their site.   A couple of them are unavailable when I click on them for some reason, but the content is available for most of them.

Topics include:

• Referee Development Through Self Assessment
  
• Tackling the Breakdown
  
• Setting the Scrum
  
• Assistant Refereeing
  
• Effective Communication
  
• Technical Zone & Assistant Refereeing
  

The USAR referees resources page also has a bunch of training videos like the one I posted yesterday on various topics.  At least some of them seem to also be available on Vimeo.  Let's see how many of them I can put on this post before Weebly complains.

Here are the 2018/19 USA GMGs.  You can also find them here and from the USA Rugby referee resources page.  USA Rugby puts this document out each year as a guide to how various aspects of the game are to be refereed.  This is the document that answers the question "when is the ball out?", among others.

USAR has promised an updated GMG for 2020, but I haven't seen it yet.

Here's a post from the MidSouth Rugby Referee Society site on communication.  http://msrrs.org/2018/02/17/effective-referee-player-communication/

 OK, let's start with Mike Cobb's scrum video from 2014.  Cobber walks you through some stuff about the scrum setup and then shows some video clips of scrums gone bad with commentary about why.  It's a really good intro to refereeing the scrum.
