In our first live scrum analysis video, we talked you through how to spot illegal binds and "boring", and today we've picked two more illegal moves you're likely to see in the weekend's rugby action.
This time we're going to show you how to spot hinging, and we'll also examine what happens when a flanker slips his bind, and illegally drives in on a prop.
Hinging can be difficult to spot, but the best way to watch out for it is to keep an eye on the hips of the props.
When a front row player hinges, all the movement will come from his waist, with no real movement in his legs.
We've also examined the flanker, and in particular what happens when he slides up the side of the scrum and drives in on the prop.
Ireland used this twice against England, with Peter O'Mahony slipping his bind from Paul O'Connell to Mike Ross, before driving in illegally on Joe Marler.
We'll be back with our final instalment from Trinity College next Wednesday, where we'll show the differences between a legally and illegally wheeled scrum.
