Which one is further to the right in the defensive line, Swann or Witt, he's the one who's impeded under the judgment. Because of the angle, the defender starts to come in to take Watmough, but furthermore can't get to Orford because Orford takes a step sideways and back almost like the perfect soccer hold up play, in fact, a similar motion that young Walsh has done a lot lately which has got him into trouble with forward passes. If Orford passes before that point, it's play on without a doubt in the world.
The player to the left also can't get across to the line that Robertson is about to run.
I didn't have any problems on game day with it, except when you judge it against other try decisions you'd have to say it was at least an inconsistent call.
