A classic case of one team playing to their strengths and stopping the other in their tracks from using theirs and capitalising of the fustration that causes.
Dura forwards didn't stand up when they were needed, if they'd managed to stop the rolling maul they would have won but they let in 3 tries(?) via the maul and just as many out wide when their defence compressed too far in to stop the maul and left gaps out wide.
Shows sometimes how rugby is a simple game, sometimes all you need is one attacking play that works well and a little bit of brains on top to easily win games.
