The two no try calls were 100% spot on. First one, Dragons player initiates contact on Shaun Lanes outside shoulder, Lane is trying to cover from the inside but can't Quite there. He gets an ankle tackle in, but it was that hold up in the defensive line that Widdop took. On the second one, the Dragons decoy makes a beeline for Ryan Hoffman who is in the defensive line looking to move up and across, contact is initiated, and instead of a straight line defensively that has pushed up, Hoffman is stopped and is behind the line presenting a staggered line and a gap which Marshall exploits. Clear obstructions both of them. Denied clear cut opportunities to stop thenDragons attackers well short of the advantage line let alone the goal line.
