Hi Nathan
1) The thrower first establishes a pivot on the central zone and then the defence taps the disc in – all other players must remain still until the check. (NOTE: We are looking at changing this rule in the future to match the USAU Rule – tapped in and then players move to the goal line)
2) The single O player can be guarded by two D players – there is no rule that prevents this – Double team only applies to the thrower.
Cheers
