Note the quotation marks...I'm only referring to what it states in the vid..the ball is not contestable.
Call it what you want is irrelevant..."dead", "play stopped", "wait for the fella to get up off the floor, back heel the ball, and then make the ball live again". What is relevant is this uncontestable routine occurs on average 600 times per game, a fragmentation many cannot adapt to.
Infact i'll go further. Once the ball in the ruck and the opposition is not trying to drive over, the team are observing the offside and surrendered to the fact that the ball is out of competition there is a time limit on how long it can remain in the ruck, something like 5 seconds. For this 5 seconds the ball is not being contested in union.
