The Brumbies indeed didn't look in the game for the most part. It was very similar to the game with the Bulls with the Brumbies not having the intensity at home compared to their opposition. They also had issues with ball security with losing a number in contact, including one that led to the great 90 m try by the Crusaders.
A couple of lessons for the Brumbies in that match and luckily they have a bye to address those before going to meet the Tahs in Sydney in 2 weeks. The Tahs should be a better side than the one they met earlier in the season.
