First, binding in the scrum. You can get creative with the scrum if you like, but there is one law you have to pay attention to - all players except the front row have to bind on to a lock. You can shift the 8 man, move the flankers forward and back on the lock, but everybody has to bind on to a lock. You should always have at least eight players in the scrum unless you have a man sent off or an injury, theoretically you can bind more people into the scrum, but no one has really figured out a good way to do that and keep the scrum together.....(otherwise we would be seeing a lot more creative scrumming).... I guess you could double your 8 man up if you like... it would be interesting to see how that would work out.  Anyway, nice try, but practice your binding if you are going to do something creative, and let the ref know what you are trying to do.

Second issue - jackling, it came up a couple of times. Only the first in to the tackle can handle the ball as the ruck forms if he remains on his feet. In a related issue, in a case where a tackle is made and a second player participates, the second man in is not entitled to remain offsides after the tackle. He must release the ball carrier, and come back through the tackle box. The first in can get to his feet and fight for the ball without being offsides. (Before the ruck forms)
