The issue is when you have a pod detaching with the ball. If its a new maul (ie change of channel) then its an obstruction issue if ball at back, or a pre-bind flying wedge issue if ball at front.
How wide is the channel? The width of the existing maul? If it wheels and pushes the BC out wide, how far is too far?
Also, if the BC detaches from the maul (whether deliberately or it fragments around them) then don‘t we just treat that as maul over and we’re in open play?
Similarly, if the BC breaks off with a single bound support peeling off with them then open play and:
- if ball with frontmost player, play on
- if ball not at front, treat as obstruction
- ball at front but second supporting player joins (or peels of with the BC so they have two bound support players) but before an opponent attempts to tackle then treat as flying wedge.
Have I got that right?
