While I have talked about how rugby works in previous posts, these videos will help further understand the game. Some of these are the videos I was shown when I first started playing rugby.

The video above goes over what rugby is, who are on the teams, and stuff like that in an entertaining British accent.
This is a good video to show to someone before they go watch their first game as it gives a gist of what is about to happen within a few short minutes if you do not have a lot of time to sit down and explain the game to them.

This next video elaborates more on tackling. Focus on the hips, because they don’t lie! You will be able to tell where the ball carrier is going to go based on where their hips are pointing and you will be able to take down even the slipperiest runner.
