We had plenty go against us in the game so you can't just grasp onto that one call, penalties that should never have been given, knock ons given against us which were stripped.
However, I'm a firm believer in the ref doesn't win or lose you games. We picked up in that last 20 minutes and Cas had put so much into the first 60 you just tired out and couldn't keep up with the pace. Absolutely out standing for the first 60 minutes though and deserved at least a point out of the game.
