"It was a good hit out [against Honda] last week to get the guys acclimatised to the heat and to see who was motivated. There were some guys who showed a lot of energy and that's what we want.
"We can't go into this game thinking it's just going to happen for us and think that playing on a wave of emotion is going to pull us through. In the end we still need to play hard for 80 minutes and some people are better at getting themselves up for these kinds of things than others. I wanted to see that and that's how we've gone.
The Blues will likely finish the season in ninth place, potentially their highest finish since 2011 when they were beaten in the semifinals by eventual champions the Reds. They will probably end up with more competition points than the Brumbies, who are guaranteed a home quarter-final, but Umaga has long reconciled himself to the competition's quirks.
"The way I look at it, you've got to be the fourth New Zealand team to have any chance of making the quarter-finals. That's all I measure ourselves on at this stage and we didn't do that."
