Just seen it your 100% right. Probably because he wanted dogs to be offside to blow a penalty in front but they all got back. They still had a solid shot at Gallen who pissed and shit all over them.
If you do watch again , ( if you could bring yourself to ) Adam Elliot had a great opportunity to stop Gallens legs at first contact but just ran along side him and watched him make another 15m , that extra distance helpedTownsend greatly.
As for Gallen getting out of the ingoal, great blocking play, someone should have taken a Ray Thomson dive, and that would have ended it right there. Not called, quick play the ball and they were off.
